Ethanethioic acid, [[(phenylmethoxy)carbonyl]amino]-, S-phenyl ester, also known as phenylmethoxycarbonylaminoethanethioate or Z-Cysteine, is a chemical compound with the molecular formula C11H11NO3S. It is a derivative of ethanethioic acid, featuring a phenylmethoxycarbonyl group attached to the amino group and a phenyl group esterified to the sulfur atom. Ethanethioic acid, [[(phenylmethoxy)carbonyl]amino]-, S-phenyl ester is commonly used in organic synthesis, particularly in peptide chemistry, as a protecting group for cysteine residues during peptide synthesis. The phenylmethoxycarbonyl (Z) group can be selectively removed under mild conditions, allowing for the deprotection of the cysteine residue. Ethanethioic acid, [[(phenylmethoxy)carbonyl]amino]-, S-phenyl ester plays a crucial role in the synthesis of various biologically active peptides and proteins, as well as in the development of new drugs and pharmaceuticals.

2899-57-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2899-57-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,9 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2899-57:
(6*2)+(5*8)+(4*9)+(3*9)+(2*5)+(1*7)=132
132 % 10 = 2
So 2899-57-2 is a valid CAS Registry Number.
