The chemical "β-(S-benzylmercapto)-β,β-cyclopentamethylenepropionyl-Gly-Phe-Val-Asn-Cys(Bzl)-Pro-Arg(Tos)-Gly-NH2" is a complex peptide compound consisting of a sequence of amino acids. It features a cyclopentamethylenepropionyl group, which is a five-carbon cyclic structure attached to the peptide backbone. The peptide includes a β-(S-benzylmercapto) group, indicating the presence of a benzyl-protected thiol group, which is often used to protect the thiol functionality of cysteine during peptide synthesis. The sequence also contains a Cys(Bzl), which is a cysteine residue with a benzyl group attached, and an Arg(Tos), which is an arginine residue with a tosyl group, a common protecting group in peptide chemistry. This specific peptide is likely used in research settings for studying protein structure, function, or as a potential therapeutic agent, given its protected amino acid residues that can be deprotected under specific conditions to reveal the native functionalities of the peptide.
The CAS Registry Mumber 81094-01-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,0,9 and 4 respectively; the second part has 2 digits, 0 and 1 respectively. Calculate Digit Verification of CAS Registry Number 81094-01: (7*8)+(6*1)+(5*0)+(4*9)+(3*4)+(2*0)+(1*1)=111 111 % 10 = 1 So 81094-01-1 is a valid CAS Registry Number.
