１０．What description method of molecular formula is adopted to NITE-CHRIP?
１０．The molecular formula in NITE-CHRIP is displayed with the method adopted by CAS and Hill method. For listing elements, Hill method is adopted in NITE-CHRIP, too. First, C is listed, second, H is listed, and subsequently, other elements are listed in alphabetical order. When the substance doesn't contain carbon, all elements are listed in alphabetical order.
Using the method by CAS, the molecular formula of multicomponent substances (salt, addition compound, mixture, copolymer, hydrate, alloy, intermetallic compound, compound of variable composition, etc.) are displayed by each component and the points connecting them.
For example, when sodium carbonate is displayed by this method, its molecular formula is "CH2O3.2Na", which is made by "CH2O3"- carbonate, "Na"- sodium, and "." connecting point.
１１．Does “Chemical Substance Name” in “General Information” on NITE-CHRIP correspond to the CA Index Name by Chemical Abstracts Services (CAS)?
１１．The Japanese and English chemical substance names in "General Information" on NITE-CHRIP are basically the IUPAC name (based on 1993 recommendations of the IUPAC nomenclature for organic compounds, and 2005 for inorganic compounds).
NITE is continuously naming and checking chemical substance names by IUPAC nomenclature on NITE-CHRIP. Some substances that are not named by the IUPAC nomenclature are associated with the CAS Registry Number. For such substances, the CA Index Name (CA IN) corresponding to the CAS Registry Number (CAS RN) is listed in NITE-CHRIP.
In addition, some chemical names in "General Information" on NITE-CHRIP are quoted from names publicized in the Official Gazette or by national and international authorities, because it is difficult to assign names by IUPAC name or CA Index Name. These chemical names may be described to a comprehensive name including multiple structures or added qualifications such as "limited to liquid ones" on NITE-CHRIP.
１２．What kind of description method is used for chemical substance names on NITE-CHRIP?
１２．Characters of displayed name: Subscripts or italicized characters are displayed as standard characters. Superscripts are displayed in brackets.
Example: 52 ⇒5(2)、λ6⇒λ(6)
For this reason, on the display, there is no distinction between position numbers indicated with superscript characters (red part) and position numbers indicated with numbers in brackets (blue part) in substance names.
Example: 4,4-dimethyl-2,6-dioxa-1,7 (1), 3,5 (1,4) -tetrabenzenaheptaphan-14,74-diamine
⇒ 4,4-dimethyl-2,6-dioxa-1,7 (1), 3,5 (1,4) -tetrabenzenaheptaphan-1 (4), 7 (4) -diamine
(Upper row: substance name in normal notation, lower row: display of the same substance name in NITE-CHRIP)
１３．There are chemical substances displaying (※1), (※2) and (※3) at the Interim Search Results (”Display by CHRIP ID and CAS RN”) . What does it mean?
(※1) The substance which matches the substance indicated by MITI number or cabinet order number when a certain condition is fulfilled. The condition is listed in the remarks column of the search result, so be sure to check it.
(※2) The substance which is regarded as CSCL: Class I Specified Chemical Substances, Class II Specified Chemical Substances, Monitoring Chemical Substances, Priority Assessment Chemical Substances by the operation notification "Implementation of the Act on the Evaluation of Chemical Substances and Regulation of Their Manufacture, etc. 3-1".
(※3) The substance which had been designated in accordance with paragraph (5) of Article 2 of CSCL: Priority Assessment Chemical Substances and later was cancelled.
For the details, please refer to the Remarks on “Search Results” screen for each chemical substance.
１４．Why is unable to download the search result when the number of CAS registry number (CAS RN) hits exceeds 5000?
１４．CAS registry numbers are the intellectual property of the American Chemical Society, Chemical Abstracts Service (CAS) division.
NITE-CHRIP operates based on CAS Information Use Policies.
CAS Information Use Policies
Individuals or groups can download and use 5000 numbers at most, so the result isn't displayed on NITE-CHRIP if the number of CAS registry number (CAS RN) hits exceeds 5000.
１５．If regulatory information is not displayed, can I decide the regulation is not applicable?
１５．NITE is sequentially linking the exemplified substances corresponding to each law or regulation using related documents or HP of the competent authorities, but not all chemical substances subject to the Laws and regulations are listed in NITE-CHRIP.
Therefore, chemical substances, whose information about the law or regulation is not displayed in NITE-CHRIP, may subject to the law or regulation.
When you can't confirm regulatory status by using NITE-CHRIP, please consult the competent authorities.

How to search for MITI number, etc.
１６．What is MITI number?
１６．MITI number is the registration number assigned to the chemical substance listed in Existing Chemicals List in the official gazette under CSCL. The chemicals in this list are called “Existing Chemical Substances” in Japan.
Moreover, MITI-numbers have been assigned to notified new chemicals since CSCL went into effect.
In addition, MITI number may also be called METI number or CSCL number.
Please refer to FAQs-Questions and Answers about CSCL in detail.
１７．How can Iconfirm whether the substance to be manufactured or imported has METI number, or not?
１７．You can investigate the current status of the chemical substance regarding CSCL with NITE-CHRIP.
From the NITE-CHRIP TOP page, click "Search by chemical " button. On the next page, search by CAS Registry Number (CAS RN). Even though you search by CAS Registry Number (CAS RN) and the search results do not come out, it does not necessarily mean that the MITI number does not exist. In that case, you need to search it by a chemical name. For searching by the chemical name, please refer to Q18 in this FAQ.
There are three combinations of CAS Registry Number (CAS RN) and MITI number posted on NITE-CHRIP as shown below.
(1) The substance of CAS RN matches exactly the substance indicated by MITI number.
(2) The substance of CAS RN is included in the substance indicated by MITI number.
(3) The substance of CAS RN matches the substance indicated by MITI number when a certain condition is fulfilled.
Regarding (3), the condition is listed in the Remarks column of the search result screen and displayed on NITE-CHRIP. Be sure to check the conditions.
For reference, please refer to this related to the combinations of CAS Registry Number (CAS RN) and MITI number.
１８．The message "There is no target data" appears after searching MITI number by CAS Registry Number (CAS RN). Does it mean that this chemical substance doesn’t have MITI number, in other words it is the newly chemical substances under CSCL?
１８．On NITE-CHRIP, chemical substances that can be confirmed by NITE from each information source are linked to appropriate numbers（e.g.: CAS RN, MITI number, etc.） in sequence, but not all chemical substances subject to MITI numbers are linked with CAS Registry Number (CAS RN). Therefore, even though you search by CAS Registry Number (CAS RN) and you get the message "There is no target data", it does not necessarily mean that the chemical substance is the newly chemical substances. In that case, you need to search for it by chemical name.
Please refer to Q2 of FAQs-Questions and Answers about CSCL in detail .
If you cannot find the MITI number from either the CAS Registry Number (CAS RN) or the chemical name, it means that there is a high possibility of the newly chemical substances under CSCL.
For reference, please refer to this document related to search by chemical name.
１９．The message, "There is an error in the input data" appears after searching by the CAS Registry Number (CAS RN). Is it a system error on NITE-CHRIP?
１９．The CAS Registry Number (CAS RN) you entered may be incorrect. Please check and enter the correct CAS Registry Number (CAS RN).
Please read this for the CAS Registry Number (CAS RN), and this for the check digit.
２０．When I imported a chemical substance, the Customs directed me to fill in the MITI number on the import declaration. What should I check at that time?
２０．First, it is necessary to confirm whether the MITI number is assigned to the chemical substance to be imported. Please refer to Q17 in this FAQ, which shows how to search for the MITI number.
If the chemical substance is assigned to MITI number except for Class I Specified Chemical Substances, it is allowed to import this chemical substance. In that case, for Class II Specified Chemical Substances, it is necessary to notify the government in advance and obtain approval for import. When importing, ｙou need to fill in MITI number on the import declaration or invoice.
For more information on procedures, please refer to FAQs-Questions and Answers about CSCL.
If there is no MITI number, it is highly likely that it is the newly chemical substances under CSCL. You need to submit a new chemical notification based on CSCL before the manufacture or import of the newly chemical substances except requirements for exemption. (Q6 of FAQs-Questions and Answers about CSCL)
２１．Please tell me how to search for ISHA number?
２１．You can also search for the ISHA number on NITE-CHRIP in a similar way to search for MITI number.
(For the details on how to search for the MITI number, please read Q17 in this FAQ.)
However, there are chemical substances that have been assigned to the ISHA number but have not been assigned to the MITI number because the notification requirements differ between the Industrial Safety and Health Act and the Chemical Substances Control Law.
Please check the website of the Ministry of Health, Labor and Welfare for the notification requirements of the Industrial Safety and Health Act.
