"O-(1,1-Dimethylethyl)-N-[(benzyloxy)carbonyl]-L-serine 4-nitrophenyl ester" is a complex organic compound with the chemical formula C21H26N2O7. It is a derivative of L-serine, an amino acid, with a 1,1-dimethylethyl (tert-butyl) group at the hydroxyl group, a benzyloxycarbonyl (Cbz) protecting group at the amino group, and a 4-nitrophenyl ester at the carboxylic acid group. O-(1,1-Dimethylethyl)-N-[(benzyloxy)carbonyl]-L-serine 4-nitrophenyl ester is often used in peptide synthesis as a protected form of L-serine, where the protecting groups can be removed under specific conditions to yield the free amino acid. The 4-nitrophenyl ester group is particularly useful as it allows for easy monitoring of the deprotection process due to the color change of the 4-nitrophenolate ion upon hydrolysis.

5545-50-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5545-50-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,4 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5545-50:
(6*5)+(5*5)+(4*4)+(3*5)+(2*5)+(1*0)=96
96 % 10 = 6
So 5545-50-6 is a valid CAS Registry Number.
