"Z(OMe)-Cys(MBzl)-Ala-Tyr-OMe" is a peptide sequence consisting of four amino acids: Cysteine (Cys), Alanine (Ala), Tyrosine (Tyr), and a terminal methoxy group (OMe). The Cys residue is modified with a benzyl group (MBzl), and the N-terminal amino group is protected by a carbobenzyloxy (Z) group, while the C-terminal carboxylic acid is also protected by a methoxy group (OMe). This specific arrangement of amino acids and protective groups is crucial for maintaining the peptide's stability and preventing unwanted side reactions during synthesis or biological studies. The sequence is often used in peptide synthesis and research, particularly in the development of pharmaceuticals and understanding protein-protein interactions.

Check Digit Verification of cas no

The CAS Registry Mumber 77834-17-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,8,3 and 4 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 77834-17:
(7*7)+(6*7)+(5*8)+(4*3)+(3*4)+(2*1)+(1*7)=164
164 % 10 = 4
So 77834-17-4 is a valid CAS Registry Number.

Total Synthesis of Bovine Pancreatic Ribonuclease A. Part 2. Synthesis of the Protected Hexatriacontapeptide Ester (Positions 89-124)

Fujii, Nobutaka,Yajima, Haruaki

, p. 797 - 803 (2007/10/02)

Commencing with the protected C-terminal pentadecapeptide of bovine pancreatic RNase, Z(OMe)-(RNase 110-124)-OBzl, chain elongation was accomplished to form the hexatriacontapeptide, Z(OMe)-(RNase 89-124)-OBzl, by six successive azide condensations of the
