N-[(benzyloxy)carbonyl]-S-[bis(4-methoxyphenyl)methyl]cysteine is a complex organic compound with the molecular formula C27H29NO6S. It is a derivative of the amino acid cysteine, featuring a benzyloxycarbonyl (Cbz) protecting group on the nitrogen atom and a bis(4-methoxyphenyl)methyl (Momp) group on the sulfur atom. N-[(benzyloxy)carbonyl]-S-[bis(4-methoxyphenyl)methyl]cysteine is often used in peptide synthesis as a protected cysteine analog, where the Cbz group prevents unwanted side reactions during the coupling process, and the Momp group serves as a protecting group for the thiol side chain. The 4-methoxyphenyl groups in the Momp moiety can be removed under mild acidic conditions, allowing for the deprotection of the cysteine residue in the final peptide product.

5191-81-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5191-81-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,9 and 1 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5191-81:
(6*5)+(5*1)+(4*9)+(3*1)+(2*8)+(1*1)=91
91 % 10 = 1
So 5191-81-1 is a valid CAS Registry Number.
