CAS Numbers

Thus, if the user wants to look for literature including requested chemicals or reactions, it is possible to query the database by the first option Chemical Substance or Reaction , The compound can be entered as a query in three different ways drawing the chemical structure in a molecule editor (Chemical Structure) searching by names or identification number, such as the CAS Number (Structure Identifier) and searching by molecular formula (Figure 5-12).

CAS Number - Chemical Abstracts Service Registry Number A CAS (Chemical Abstracts Service) Registry Number is a unique identifier that tells you, for example, that aeetone and dimethyl ketone are actually the same substance. The Chemical Abstracts Service is a division of the American Chemical Society. OSHA only requires certain items on an MSDS and a CAS number is not one of them. However, authors of MSDS s are allowed to add additional information, such as the CAS number, if they desire. The numbers you see on trucks on the highway are not CAS Numbers, butU.S. Department of Transportation (DOT) codes, which are not necessarily specific to each chemical. Their aim is to assist emergency responders. 

Enter the Chemical Abstracts Service (CAS) registry number in Section 1.2 exactly as it appears in Table II, pages 40-48, for the chemical being reported. CAS numbers are cross-referenced with an alphabetical list of chemical names in Table II of these instructions, tf you are reporting one of the chemical categories in Table II (e.g., copper compounds), enter not applicable, NA, In the CAS number space. 

If you are making a trade secret claim, you must report the CAS number on your unsanitized Form R and unsanitized substantiation form. Do not include the CAS number on your sanitized Form R and sanitized substantiation form (see page 1 for more information). 

Enter the name of the chemical or chemical category exactly as it appears in Table II. If the chemical name is followed by a synonym in parentheses, report the chemical by the name that directly follows the CAS number (i.e., not the synonym)... 

Do not list the name of a chemical that does not appear in Table II, such as individual members of a reportable category. For example, if you use silver nitrate, do not report silver nitrate with its CAS number. Report this chemical as "silver compounds which has no CAS number.

CAS number and the chemical name reported on page three must exactly match the listed section 313 CAS number and chemical name. Chemical categories should not be reported with a CAS number. A generic chemical name should only be provided if you are claiming the section 313 chemical identity as trade secret. Chemical names should be taken directly from the list in this document (see pages 40-48). Mixture names are to be entered in Part III, Section 1.4 if that is the sole identification. Mixture names that include the name (or CAS number) of one or more section 313 chemical(s) are not valid.

The purpose of this letter Is to inform you that a product that we sell to you. Furniture Lacquer KX2-1390, contains 20 percent toluene (Chemical Abstracts Service (CAS) number 108-88-3). We are required to notify you of the presence of toluene in the product under section 313 of the Emergency Planning and Community Right-to-Know Act of 1986. This law requires certain manufacturers to report on annual emissions of specified toxic chemicals and chemical categories.
