CAS Numbers are assigned by the Chemical Abstracts Service when a new chemical is reported in the scientific literature. The process involves:
Identification: The chemical must be clearly described in terms of its molecular structure. Database Entry: Once identified, the substance is entered into the CAS Registry, and a unique number is generated. Publication: The CAS Number is published and made available to the scientific community.
This structured process ensures that each chemical substance has a distinct and consistent identifier.
