Research catalogs use a specific vocabulary: compound name, sequence reference, CAS number, lot or batch identifier, and container format. Each of these describes what a product is, not what it does.
A CAS number is a registry identifier assigned to a chemical substance. It is useful for confirming that a listing refers to the substance you intended to source, particularly where multiple naming conventions exist.
Lot and batch identifiers connect a physical unit back to the documentation associated with it. When you compare a listing to a document, these identifiers are the link.
