"Z(OMe)-Asn-Cys(MBzl)-Ala-Tyr-OMe" is a peptide sequence consisting of five amino acids: N-benzyloxycarbonyl (Z)-protected asparagine (Asn), N-methoxy (OMe)-protected cysteine (Cys) with a benzyl (MBzl) group, alanine (Ala), and tyrosine (Tyr), with a methoxy (OMe) group at the C-terminus. This specific arrangement of amino acids is designed to protect certain functional groups during chemical synthesis or biological studies, allowing for controlled reactions and preventing unwanted side reactions. The Z group on asparagine and the OMe group on cysteine are protecting groups that can be removed under specific conditions to reveal the free amino acid side chains. The MBzl group on cysteine is another protecting group that shields the thiol group, which is crucial for preventing disulfide bond formation until the desired time. This peptide sequence is often used in the synthesis of larger peptides or proteins, where the precise control over the reactivity of each amino acid is essential for obtaining the desired product.

Check Digit Verification of cas no

The CAS Registry Mumber 77834-33-4 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, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77834-33:
(7*7)+(6*7)+(5*8)+(4*3)+(3*4)+(2*3)+(1*3)=164
164 % 10 = 4
So 77834-33-4 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
