"Z(OMe)-Ser-Ser-Lys(Z)-OMe" is a peptide sequence consisting of four amino acids: N-(9-fluorenylmethoxycarbonyl)-O-methyl-L-serine (Z(OMe)-Ser), L-serine (Ser), L-lysine (Lys) with a 9-fluorenylmethoxycarbonyl group (Lys(Z)), and a terminal O-methyl group (OMe). This specific arrangement of amino acids is characterized by the presence of two serine residues, which are hydrophilic and uncharged, flanking a lysine residue with a protecting group, indicating that it may be used in peptide synthesis to control the reactivity of the lysine side chain. The terminal O-methyl group suggests that this peptide is designed to be soluble in organic solvents or to have specific interactions in a biological context. The sequence is likely to be used in the synthesis of larger peptides or proteins, where the protecting groups can be removed at appropriate stages to allow for further reactions or folding.

Check Digit Verification of cas no

The CAS Registry Mumber 77834-21-0 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 1 respectively.
Calculate Digit Verification of CAS Registry Number 77834-21:
(7*7)+(6*7)+(5*8)+(4*3)+(3*4)+(2*2)+(1*1)=160
160 % 10 = 0
So 77834-21-0 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
