S-Ethylaminocarbonyl-N-benzyloxycarbonyl-L-cysteine, also known as Seoc-Z-Cys or Z-Cys(Seoc)-OH, is a chemical compound that serves as a protected amino acid in peptide synthesis. It is a derivative of the naturally occurring amino acid L-cysteine, where the thiol group is protected by an S-ethylaminocarbonyl (Seoc) group and the amino group is protected by a benzyloxycarbonyl (Z) group. S-Ethylaminocarbonyl-N-benzyloxycarbonyl-L-cystein is crucial in the synthesis of peptides and proteins, as the protecting groups prevent unwanted side reactions during the assembly process. The Seoc group is selectively removable under mild conditions, allowing for the controlled deprotection of the cysteine residue in the final product. S-Ethylaminocarbonyl-N-benzyloxycarbonyl-L-cystein is widely used in the pharmaceutical and biotechnology industries for the synthesis of therapeutic peptides and proteins with specific functionalities.

4909-59-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4909-59-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,0 and 9 respectively; the second part has 2 digits, 5 and 9 respectively.Calculate Digit Verification of CAS Registry Number 4909-59:
(6*4)+(5*9)+(4*0)+(3*9)+(2*5)+(1*9)=115
115 % 10 = 5
So 4909-59-5 is a valid CAS Registry Number.
