What Does CASRN Stand For?

CASRN stands for Chemical Abstracts Service Registry Number

CASRN, or Chemical Abstracts Service Registry Number, is a unique numerical identifier assigned to every chemical substance recorded in the Chemical Abstracts database. This number, typically consisting of up to 10 digits separated by hyphens, facilitates the precise identification, tracking, and cataloging of chemical compounds, enabling researchers, regulatory bodies, and industry professionals to access detailed information about each substance quickly and efficiently. CASRNs are widely used in scientific literature, regulatory submissions, and chemical inventory systems.
