Z-Cys(BzlOMe)-ONSu, also known as N-benzyloxycarbonyl-S-(4-methoxybenzyl)-L-cysteine N-succinimidyl ester, is a chemical compound derived from the amino acid cysteine. It features a benzyloxycarbonyl (Z) protecting group on the amino group, a 4-methoxybenzyl (BzlOMe) protecting group on the thiol group, and a succinimidyl ester (ONSu) reactive group. Z-Cys(BzlOMe)-ONSu is commonly used in peptide synthesis and protein modification, as the protecting groups can be selectively removed under mild conditions, allowing for controlled coupling reactions. The succinimidyl ester group is particularly reactive towards primary amines, making it a useful tool for conjugating peptides or proteins to other molecules, such as antibodies or fluorescent tags, in biological research and drug development.

Check Digit Verification of cas no

The CAS Registry Mumber 77374-43-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,3,7 and 4 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77374-43:
(7*7)+(6*7)+(5*3)+(4*7)+(3*4)+(2*4)+(1*3)=157
157 % 10 = 7
So 77374-43-7 is a valid CAS Registry Number.
