CAS 420-04-2 Cyanamide
CAS 420-04-2 · EC 206-992-3 · Index No 615-013-00-2
Where CAS 420-04-2 appears: every table entry that prints it among its identifiers, in the newest version of each act this record holds, and every recorded change to those entries. Many entries name a group of substances and print no number, so absence here is not absence from the law. Not legal advice.
