N-(S-Acetyl-N-(N'-benzyloxycarbonyl-glycyl)-cysteinyl)-glycin-ethylester is a complex organic compound with the molecular formula C21H28N2O8S. It is a derivative of the amino acid cysteine, featuring an acetyl group attached to the sulfur atom, a benzyloxycarbonyl-protected glycine residue, and an additional glycine unit. The molecule is further functionalized with an ethyl ester group, which can be hydrolyzed under basic conditions to yield the corresponding carboxylic acid. N-(S-Acetyl-N-(N'-benzyloxycarbonyl-glycyl)-cysteinyl)-glycin-ethylester is often used in peptide synthesis as a building block, where the protecting groups can be selectively removed to facilitate the formation of peptide bonds. The benzyloxycarbonyl group serves to protect the amino group of the glycine, preventing unwanted side reactions during synthesis, while the acetyl group protects the thiol group of the cysteine, which is crucial for maintaining the integrity of the molecule during peptide assembly.

Check Digit Verification of cas no

The CAS Registry Mumber 3196-74-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,9 and 6 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 3196-74:
(6*3)+(5*1)+(4*9)+(3*6)+(2*7)+(1*4)=95
95 % 10 = 5
So 3196-74-5 is a valid CAS Registry Number.
