The chemical sequence "Z(OMe)-Cys(MBzl)-Arg(MBS)-Glu(OBzl)-Thr-Gly-NHNH-Troc" represents a peptide with a specific arrangement of amino acids and protective groups. Z(OMe) stands for a carbobenzoxy group with a methoxyethyl group, which protects the cysteine (Cys) residue. MBzl indicates a benzyl group protecting the cysteine, while MBS stands for a 4-methylbenzenesulfonyl group protecting the arginine (Arg). OBzl represents a benzyl group protecting the glutamic acid (Glu). The sequence continues with threonine (Thr), glycine (Gly), and ends with a trityl (Troc) group protecting the terminal amine group. This peptide is designed with specific protective groups to prevent unwanted side reactions during synthesis, and the sequence of amino acids determines its structure and potential biological activity.

Check Digit Verification of cas no

The CAS Registry Mumber 77693-85-7 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, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 77693-85:
(7*7)+(6*7)+(5*6)+(4*9)+(3*3)+(2*8)+(1*5)=187
187 % 10 = 7
So 77693-85-7 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
