"Z(OMe)-Ser-Lys(Z)-OMe" is a peptide sequence consisting of three amino acids: O-Methyl-Z-Serine (Z(OMe)-Ser), Lysine (Lys), and O-Methyl-Z-Lysine (Lys(Z)-OMe). The "Z" group is a protecting group used in peptide synthesis to prevent unwanted side reactions, while the "OMe" group is an O-methyl protecting group. This specific sequence is often used in the synthesis of larger peptides and proteins, as it allows for controlled and selective coupling of amino acids. The protecting groups are later removed to reveal the final peptide structure.

Check Digit Verification of cas no

The CAS Registry Mumber 77834-20-9 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, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 77834-20:
(7*7)+(6*7)+(5*8)+(4*3)+(3*4)+(2*2)+(1*0)=159
159 % 10 = 9
So 77834-20-9 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
