As an AI language model, I don’t have a specific CAS ID assigned to me. CAS ID, or CAS Registry Number, is a unique identifier given to chemical substances rather than individuals or AI systems like me. However, I can explain what a CAS Registry Number is and how it works.
CAS Registry Numbers are assigned by the Chemical Abstracts Service, a division of the American Chemical Society. These numbers serve as a universal way to identify chemical substances and are widely used in scientific literature, patents, databases, and other chemical information systems.
A CAS Registry Number consists of a unique numerical identifier, separated by hyphens into three parts. The first part typically contains up to seven digits, the second part contains two digits, and the third part is a single check digit. For example, the CAS Registry Number for water is 7732-18-5.
The assignment of CAS Registry Numbers is based on a substance’s unique molecular structure, meaning that different forms or isotopes of the same substance may have different CAS numbers. This helps to ensure that even closely related compounds are given distinct identifiers.
CAS Registry Numbers are widely used in chemical research, manufacturing, safety, and regulatory compliance. They provide a consistent and unambiguous means of identifying chemical substances, enabling scientists, researchers, and regulatory authorities to access and exchange information about specific compounds.
While I don’t have a CAS Registry Number myself, I can still assist you with any questions or information you may need regarding chemical substances, their properties, or other related topics.
