The chemical sequence "Tyr(Bzl)-Phe-Gln-Asn-Cys(Bzl)-Pro-D-Arg(Tos)-Gly-NH2" represents a peptide, which is a short chain of amino acids linked by peptide bonds. In this specific sequence, each abbreviation corresponds to a particular amino acid with a modifying group: - Tyr(Bzl): Tyrosine with a benzyl group. - Phe: Phenylalanine. - Gln: Glutamine. - Asn: Asparagine. - Cys(Bzl): Cysteine with a benzyl group. - Pro: Proline. - D-Arg(Tos): D-arginine with a tosyl group. - Gly: Glycine. - NH2: Amino group at the end of the peptide chain. This peptide is a synthetic construct, likely designed for specific biological or pharmaceutical purposes, given the presence of non-natural amino acids (D-arginine) and protective groups (benzyl and tosyl) that are commonly used in peptide synthesis to prevent unwanted side reactions and to protect certain functional groups until a later stage of the synthesis process.

Check Digit Verification of cas no

The CAS Registry Mumber 81131-77-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,1,3 and 1 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 81131-77:
(7*8)+(6*1)+(5*1)+(4*3)+(3*1)+(2*7)+(1*7)=103
103 % 10 = 3
So 81131-77-3 is a valid CAS Registry Number.

Design of potent and selective antagonists of the vasopressor responses to arginine-vasopressin

Manning,Lammek,Kruszynski,Seto,Sawyer

, p. 408 - 414 (2007/10/02)

The authors have synthesized eight new 1-β,β-dialkyl-substituted analogues of [1-deamino]arginine-vasopressin (dAVP) to determine some of the structural features that account for antivasopressor potency and that improve selectivity by reducing antidiureti
