"Z(OMe)-Gln-Ser-Tyr-OMe" is a peptide sequence consisting of four amino acids: N-benzyloxycarbonyl (Z) protected glutamine (Gln), serine (Ser), and tyrosine (Tyr), with a methoxy (OMe) group at the N-terminus and C-terminus. This specific arrangement of amino acids is significant in peptide chemistry, as it can be part of larger bioactive molecules or used in the study of peptide synthesis and structure. The Z group is a protecting group that shields the amino group of glutamine, preventing unwanted side reactions during peptide synthesis, while the OMe groups at both ends of the peptide serve to cap the molecule, often stabilizing it and preventing further elongation. This particular sequence may be of interest in pharmaceutical research, as it could potentially be a part of a drug candidate or a probe for studying biological interactions.

Check Digit Verification of cas no

The CAS Registry Mumber 77703-03-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,7,0 and 3 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77703-03:
(7*7)+(6*7)+(5*7)+(4*0)+(3*3)+(2*0)+(1*3)=138
138 % 10 = 8
So 77703-03-8 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
