"Z-Trp-Gly-Gly-Gly-Gly-Cys(Trt)-OtBu" is a peptide compound consisting of seven amino acids: Z-protected tryptophan (Trp), four glycines (Gly), and a trityl-protected cysteine (Cys) with a tert-butyl (tBu) group. The "Z" group is a protecting group for the N-terminus of the peptide, while the "Trt" group protects the thiol group of the cysteine residue. This specific sequence and protection scheme are designed to prevent unwanted side reactions during peptide synthesis, ensuring that the peptide maintains its integrity until the desired point of deprotection. The compound is often used in the synthesis of larger peptides or proteins, where precise control over the reactivity of individual amino acid residues is crucial.

Check Digit Verification of cas no

The CAS Registry Mumber 77657-00-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,6,5 and 7 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 77657-00:
(7*7)+(6*7)+(5*6)+(4*5)+(3*7)+(2*0)+(1*0)=162
162 % 10 = 2
So 77657-00-2 is a valid CAS Registry Number.

248. Iodine Oxidation of S-Trityl- and S-Acetamidomethyl-cysteine-peptides Containing Tryptophan: Conditions Leading to the Formation of Tryptophan-2-thioethers

Sieber, Peter,Kamber, Bruno,Riniker, Bernhard,Rittel, Werner

, p. 2358 - 2363 (1980)

Cystine peptides are conveniently prepared from S-acetamidomethyl- or S-trityl-protected cysteine derivatives by direct oxidation with iodine.Since the reaction proceeds through the formation of sulfenyl iodides, these highly reactive goups may substitute
