Z-Gln-Cys(Bzl) is a synthetic peptide consisting of two amino acids, glutamine (Gln) and cysteine (Cys), with a benzyl (Bzl) protecting group on the cysteine residue. Z-Gln-Cys(Bzl) is often used in peptide synthesis and research, as the benzyl group protects the thiol group of cysteine from unwanted side reactions, such as oxidation or disulfide bond formation. The Z group, or carbobenzoxy group, is a temporary protecting group for the amino group of glutamine, which is crucial for preventing peptide bond formation during synthesis. Once the desired peptide sequence is achieved, the protecting groups can be removed to reveal the free amino and thiol groups, allowing for further reactions or studies. Z-Gln-Cys(Bzl) plays a significant role in the development of new therapeutic peptides and understanding protein structure and function.

Check Digit Verification of cas no

The CAS Registry Mumber 16869-67-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,8,6 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 16869-67:
(7*1)+(6*6)+(5*8)+(4*6)+(3*9)+(2*6)+(1*7)=153
153 % 10 = 3
So 16869-67-3 is a valid CAS Registry Number.
