L-Cysteine, N-[(1,1-dimethylethoxy)carbonyl]-, benzoate (ester) is a complex organic compound with the chemical formula C15H21NO4S. It is a derivative of L-cysteine, an amino acid that contains a thiol group (-SH) and is essential for the synthesis of proteins. The compound is characterized by the presence of a benzoate ester group, which is attached to the N-terminus of the L-cysteine molecule through a 1,1-dimethylethoxycarbonyl (also known as a tert-butyloxycarbonyl or BOC) protecting group. This protecting group is commonly used in peptide synthesis to prevent unwanted side reactions and ensure the correct sequence of amino acids. The benzoate ester group further modifies the compound's properties, making it a valuable intermediate in the synthesis of various pharmaceuticals and biologically active molecules.

6233-75-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6233-75-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,3 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.Calculate Digit Verification of CAS Registry Number 6233-75:
(6*6)+(5*2)+(4*3)+(3*3)+(2*7)+(1*5)=86
86 % 10 = 6
So 6233-75-6 is a valid CAS Registry Number.
