"Z(OMe)-Val-Gln-Ala-NHNH-Troc" is a peptide sequence consisting of five amino acids: Z(OMe), Val, Gln, Ala, and NHNH, with a Troc protecting group. Z(OMe) represents a benzyloxycarbonyl (Z) group with a methoxyethyl (OMe) substitution, which is commonly used to protect the N-terminal amino group during peptide synthesis. Val stands for valine, an essential amino acid with a branched-chain structure. Gln is glutamine, a non-essential amino acid that plays a crucial role in various metabolic processes. Ala is alanine, a simple amino acid with a single methyl side chain. NHNH indicates a terminal amino group, which can be involved in peptide bond formation. The Troc protecting group (2,2,2-trichloroethoxycarbonyl) is used to protect the side chain amino group of the peptide, preventing unwanted side reactions during synthesis. This sequence is likely to be a part of a larger peptide or protein, with the protecting groups ensuring proper folding and function upon synthesis completion.

Check Digit Verification of cas no

The CAS Registry Mumber 77694-04-3 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 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 77694-04:
(7*7)+(6*7)+(5*6)+(4*9)+(3*4)+(2*0)+(1*4)=173
173 % 10 = 3
So 77694-04-3 is a valid CAS Registry Number.

Total Synthesis of Bovine Pancreatic Ribonuclease A. Part 4. Synthesis of the Protected Tetraoctacontapeptide Ester (Positions 41-124)

Fujii, Nobutaka,Yajima, Haruaki

, p. 811 - 818 (2007/10/02)

Commencing with the protected hexapentacontapeptide corresponding to the sequence Z(OMe)-(69-124)-OBzl of bovine pancreatic RNase A, chain elongation was carried out to the tetraoctacontapeptide, Z(OMe)-(RNase 41-124)-OBzl, by seven successive azide conde
