"Z(OMe)-Cys(MBzl)-Tyr-OMe" is a peptide sequence consisting of four amino acid residues: Z(OMe), Cys(MBzl), Tyr, and OMe. Z(OMe) represents a protected form of the amino acid methionine, where the sulfur atom is blocked by a benzyl group (Bzl) and the side chain is further protected by a methoxy group (OMe). Cys(MBzl) is a cysteine residue with a benzyl protecting group on its thiol side chain. Tyr is the abbreviation for the amino acid tyrosine, and OMe stands for the methoxy group attached to the terminal amino acid. This specific sequence is often used in peptide synthesis, where the protecting groups are crucial for controlling the reactivity of the amino acids and preventing unwanted side reactions during the assembly process. The sequence is of interest in chemical biology and medicinal chemistry for its potential applications in drug development and understanding protein interactions.

Check Digit Verification of cas no

The CAS Registry Mumber 77693-91-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,6,9 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 77693-91:
(7*7)+(6*7)+(5*6)+(4*9)+(3*3)+(2*9)+(1*1)=185
185 % 10 = 5
So 77693-91-5 is a valid CAS Registry Number.

Total Synthesis of Bovine Pancreatic Ribonuclease A. Part 3. Synthesis of the Protected Hexapentacontapeptide Ester (Positions 69-124)

Fujii, Nobutaka,Yajima, Haruaki

, p. 804 - 810 (2007/10/02)

Commencing with the protected hexatriacontapeptide, corresponding to the sequence of bovine pancreatic RNase A, Z(OMe)-(RNase 89-124)-OBzl, chain elongation was carried out to the hexapentacontapeptide stage, Z(OMe)-(RNase 69-124)-OBzl, by six successive
