Z-Cys(Sub)-OTcp, also known as N-benzyloxycarbonyl-L-cysteine (S-2-oxo-1,3-thiazolidinyl)-O-(2,2,2-trichloroethyl) ester, is a synthetic chemical compound. It is a derivative of L-cysteine, an amino acid, with a benzyloxycarbonyl (Z) protecting group, a 2-oxo-1,3-thiazolidinyl substituent, and a 2,2,2-trichloroethyl (OTcp) ester group. Z-Cys(Sub)-OTcp is often used in peptide synthesis as a building block, where the protecting groups help control the reactivity of the cysteine side chain and the ester group facilitates coupling reactions. The Z group protects the amino group, preventing unwanted side reactions, while the OTcp group is used to protect the carboxylic acid, allowing for selective activation and coupling in peptide synthesis.

Check Digit Verification of cas no

The CAS Registry Mumber 59188-95-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,1,8 and 8 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 59188-95:
(7*5)+(6*9)+(5*1)+(4*8)+(3*8)+(2*9)+(1*5)=173
173 % 10 = 3
So 59188-95-3 is a valid CAS Registry Number.
