The chemical "Z-Pyr-Ala-Asp(OBzl)-Pro-Lys(Z)-Thr-Phe-Tyr-Gly-Leu-Met(O)-NH2" is a peptide sequence consisting of 12 amino acids. It is a synthetic compound with a specific arrangement of amino acids, each denoted by its three-letter code. The sequence starts with Z-Pyr, which is likely a modified form of pyroglutamic acid (also known as pyrrolidone carboxylic acid), and is followed by alanine (Ala), aspartic acid with a benzyl ester group (Asp(OBzl)), proline (Pro), lysine with a benzyl group (Lys(Z)), threonine (Thr), phenylalanine (Phe), tyrosine (Tyr), glycine (Gly), leucine (Leu), and methionine with an oxide group (Met(O)). The sequence ends with an amide group (NH2). This peptide may have specific biological activity or be used in research to study protein-protein interactions or as a potential therapeutic agent. The presence of protecting groups like benzyl (Bzl) and oxide (O) indicates that this peptide is likely used in synthetic organic chemistry for the stepwise assembly of larger peptide structures or for protecting certain functional groups during synthesis.

Check Digit Verification of cas no

The CAS Registry Mumber 81657-33-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,6,5 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 81657-33:
(7*8)+(6*1)+(5*6)+(4*5)+(3*7)+(2*3)+(1*3)=142
142 % 10 = 2
So 81657-33-2 is a valid CAS Registry Number.
