N-(S-Benzyl-N-benzyloxycarbonyl-L-cysteinyl)-glycin-(glykolsaeureamid-ester) is a complex organic compound that is a derivative of glycine, an amino acid. It features a benzyl group attached to the sulfur atom of a cysteine residue, which is further protected by a benzyloxycarbonyl group. N-(S-Benzyl-N-benzyloxycarbonyl-L-cysteinyl)-glycin-(glykolsaeureamid-ester) is often used in peptide synthesis as a protecting group to prevent unwanted side reactions, particularly for cysteine residues that are prone to oxidation. The glycol acid amide ester group indicates the presence of an ester linkage with glycolic acid, which can be used to control the reactivity of the molecule in chemical reactions. N-(S-Benzyl-N-benzyloxycarbonyl-L-cysteinyl)-glycin-(glykolsaeureamid-ester) is a valuable tool in the field of organic chemistry and biochemistry, particularly in the synthesis of peptides and proteins where precise control over the reactivity of functional groups is crucial.

Check Digit Verification of cas no

The CAS Registry Mumber 4816-91-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,1 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4816-91:
(6*4)+(5*8)+(4*1)+(3*6)+(2*9)+(1*1)=105
105 % 10 = 5
So 4816-91-5 is a valid CAS Registry Number.
