Z-Cystein(Z)-benzylester, also known as N-benzyloxycarbonyl-L-cysteine benzylester, is a chemical compound with the molecular formula C17H19NO4S. It is a protected form of cysteine, an amino acid, where the thiol group is blocked by a benzyl group and the amino group is protected by a benzyloxycarbonyl (Z) group. Z-Cystein(Z)-benzylester is commonly used in peptide synthesis as a building block, allowing for the controlled formation of peptide bonds without unwanted side reactions. The benzyl protecting groups can be removed under specific conditions to yield the free cysteine residue, which is crucial for the formation of disulfide bonds in peptides and proteins. Z-Cystein(Z)-benzylester plays a significant role in the synthesis of biologically active peptides and proteins, contributing to research in fields such as pharmaceuticals, biochemistry, and molecular biology.

Check Digit Verification of cas no

The CAS Registry Mumber 73504-32-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,5,0 and 4 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 73504-32:
(7*7)+(6*3)+(5*5)+(4*0)+(3*4)+(2*3)+(1*2)=112
112 % 10 = 2
So 73504-32-2 is a valid CAS Registry Number.
