δ-Carbobenzoxy-N-(p-methoxy-benzyloxycarbonyl)-L-cystein is a complex organic compound with the chemical formula C23H23NO6S. It is a derivative of the amino acid L-cysteine, featuring a carbobenzoxy (Cbz) group at the N-terminus and a p-methoxy-benzyloxycarbonyl (Mboc) group at the δ-position. δ-Carbobenzoxy-N-(p-methoxy-benzyloxycarbonyl)-L-cystein is widely used in peptide synthesis as a protecting group for cysteine residues, preventing unwanted side reactions and ensuring the correct formation of peptide bonds. The Mboc group is particularly useful for protecting the thiol group of cysteine, which is essential for maintaining the integrity of the peptide structure during synthesis. Once the peptide is fully assembled, the protecting groups can be removed under specific conditions to reveal the native cysteine residue, allowing for further functionalization or biological activity.

Check Digit Verification of cas no
The CAS Registry Mumber 23931-66-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,9,3 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.Calculate Digit Verification of CAS Registry Number 23931-66:
(7*2)+(6*3)+(5*9)+(4*3)+(3*1)+(2*6)+(1*6)=110
110 % 10 = 0
So 23931-66-0 is a valid CAS Registry Number.
