In the protocol example, what is the CAS number associated with the test substance All-Slide3?

Explanation:
CAS numbers are the unique numeric identifiers assigned by the Chemical Abstracts Service to chemical substances, allowing exact materials to be identified across protocols and safety documents. In this example, the test substance All-Slide3 is linked to the CAS 7001-12-3891, which uniquely identifies that chemical within the protocol. The other options don’t fit CAS format or identify the substance: EZ-509 is more like a product or catalog code, All-Slide3 is the name itself, and Bes-Tever appears to be another substance name. Because CAS numbers are three-part numeric identifiers with hyphens, 7001-12-3891 is the identifier that unambiguously corresponds to All-Slide3 in this context.
