Q. What is a CAS Registry Number®?
A CAS Registry Number (CAS RN) is the industry standard for chemical substances, providing a unique identifier for scientists across all disciplines related to chemistry and life sciences. A CAS RN has been referred to as the gold standard of the scientific information industry.
Q. How does CAS Assign Registry Numbers?
A CAS Registry Number is assigned to a substance when it is identified as novel and is added to the CAS REGISTRY database. Numbers are assigned using a special algorithm, developed by CAS.
Q. What is meant by the phrase “novel compounds?”
CAS Registry Numbers are assigned when CAS scientists identify a unique chemical substance in the literature that has not been registered by CAS previously. Therefore, your discovery represents a “novel compound” in our data collection.
