Z-Val-Cys(Bzl)-ONB is a synthetic peptide compound consisting of three amino acids: Valine (Val), Cysteine (Cys) with a benzyl (Bzl) protecting group, and Norleucine (ONB). The "Z" prefix indicates the presence of a carbobenzoxy (Cbz) group, which is a temporary protecting group used in peptide synthesis to prevent unwanted side reactions. Z-Val-Cys(Bzl)-ONB is commonly used in the field of organic chemistry and peptide synthesis, particularly in the study of protein structure and function, as well as in the development of new drugs and therapeutics. The benzyl group on the cysteine residue serves to protect the thiol group, which is crucial for maintaining the integrity of the peptide during synthesis, while the norleucine residue acts as a placeholder or a structural component in the peptide sequence.
The CAS Registry Mumber 3064-93-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,6 and 4 respectively; the second part has 2 digits, 9 and 3 respectively. Calculate Digit Verification of CAS Registry Number 3064-93: (6*3)+(5*0)+(4*6)+(3*4)+(2*9)+(1*3)=75 75 % 10 = 5 So 3064-93-5 is a valid CAS Registry Number.
