Search Tip of the Month
The gold standard for chemical information, CAS REGISTRY, contains more than 68 million unique organic and inorganic chemical substances, and more than 63 million sequences. Substance records with incompletely known structures or complex mixtures contain the Editor Note field (/ENTE), which provides more information or gives a description to better understand the structure and its use. In this example, learn about the Usefulness of the Editor Note Field in CAS REGISTRY Database.

CAS Customer Center Q&A


Each month we’ll provide answers to real customer questions.

Q. Why do some substances in CAS REGISTRY have zero references? How can I learn more about these substances?

A. Records in REGISTRY represent substances indexed for the CAS databases (CASM/CAplusSM, CASREACT®, CHEMCATS®, CHEMLIST®, MARPAT®) and other databases in products such as SciFinder® and STN. Substances that come from sources other than literature or patent publications may not contain any references. CAS indexes these substances to support registration policies, chemical libraries, chemical catalogs, web sources, reaction databases and data collections not represented in STN.

To learn more about a substance in CAS REGISTRY that does not have any literature or patent references in an STN database, consult the following fields:

  • Source of Registrations (SR)

    For CAS Registry Numbers® 97314-93-7 and higher, the SR field indicates the reason for first registering the substance. You can EXPAND or SEARCH the content of the SR field.

  • Class Identifier (CI)

    For substances registered to support CAS registration policies, the CI field may provide additional insights as to why the substance was registered.
