N-Carbobenzoxy-S-benzoyl-L-cysteinyl-glycinethylester, also known as Z-CBZ-Cys-Gly-OEt, is a synthetic peptide derivative that plays a significant role in peptide synthesis. N-Carbobenzoxy-S-benzoyl-L-cysteinyl-glycinethylester is a protected amino acid, where the N-terminal is protected by a carbobenzoxy (Cbz) group, and the S-terminal is protected by a benzoyl (Bz) group. The L-cysteinyl-glycinethylester part of the molecule consists of L-cysteine and glycine, with an ethyl ester group attached to the carboxylic acid. This specific arrangement of protecting groups and amino acids allows for controlled peptide bond formation during solid-phase peptide synthesis, ensuring that the peptide sequence is formed with high fidelity and purity. The use of such protected amino acid derivatives is crucial for the successful synthesis of complex peptides and proteins in research and pharmaceutical applications.

3303-49-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 3303-49-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,0 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.Calculate Digit Verification of CAS Registry Number 3303-49:
(6*3)+(5*3)+(4*0)+(3*3)+(2*4)+(1*9)=59
59 % 10 = 9
So 3303-49-9 is a valid CAS Registry Number.
