Benzyloxycarbonyl-S-benzyl-L-cystein-(2,4,6-trimethyl-benzylester) is a complex organic compound with the molecular formula C31H35NO4S. It is a derivative of the amino acid L-cysteine, featuring a benzyloxycarbonyl (Cbz) protecting group, a benzyl (Bn) group on the sulfur atom, and a 2,4,6-trimethylbenzyl (Tmb) ester group. Benzyloxycarbonyl-S-benzyl-L-cystein-(2,4,6-trimethyl-benzylester) is commonly used in peptide synthesis as a protected form of cysteine, which allows for the controlled formation of disulfide bonds and the synthesis of cyclic peptides. The protecting groups can be removed under specific conditions to reveal the free cysteine residue, facilitating further chemical reactions or biological studies.
The CAS Registry Mumber 7750-48-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,5 and 0 respectively; the second part has 2 digits, 4 and 8 respectively. Calculate Digit Verification of CAS Registry Number 7750-48: (6*7)+(5*7)+(4*5)+(3*0)+(2*4)+(1*8)=113 113 % 10 = 3 So 7750-48-3 is a valid CAS Registry Number.
