"Benzyloxycarbonyl-L-aspartic acid α-tert-butyl β-p-nitrophenyl ester" is a complex organic compound with the chemical formula C22H24N2O9. It is a derivative of aspartic acid, an amino acid, where the α-carboxyl group is protected by a benzyloxycarbonyl (Cbz) group, and the β-carboxyl group is esterified with a tert-butyl group and a p-nitrophenyl group. benzyloxycarbonyl-L-aspartic acid α-tert-butyl β-p-nitrophenyl ester is often used in peptide synthesis as a protected form of aspartic acid, allowing for the controlled formation of peptide bonds. The p-nitrophenyl ester group serves as a reporter group, which can be used to monitor the progress of peptide bond formation due to its UV absorbance. The tert-butyl group provides a stable protecting group that can be removed under acidic conditions without affecting the peptide backbone. benzyloxycarbonyl-L-aspartic acid α-tert-butyl β-p-nitrophenyl ester is a valuable tool in the field of biochemistry and pharmaceuticals for the synthesis of complex peptide structures.

Check Digit Verification of cas no

The CAS Registry Mumber 6997-15-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,9 and 7 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 6997-15:
(6*6)+(5*9)+(4*9)+(3*7)+(2*1)+(1*5)=145
145 % 10 = 5
So 6997-15-5 is a valid CAS Registry Number.
