N^β-Benzyliden-N^α-benzyloxycarbonyl-glycyl-hydrazinoessigsaeure-aethylester is a complex organic compound with the molecular formula C21H24N2O6. It is a derivative of hydrazinoacetic acid, featuring a benzyliden group at the β-nitrogen and a benzyloxycarbonyl-glycyl moiety at the α-nitrogen. The molecule also contains an ethyl ester group, which is attached to the carboxylic acid functionality of the hydrazinoacetic acid core. N^β-Benzyliden-N^α--hydrazinoessigsaeure-aethylester is often used in peptide synthesis as a protecting group strategy, where the benzyloxycarbonyl (Z) group protects the amino group, and the ethyl ester provides a means for controlled hydrolysis under mild acidic conditions. The structure of N^β-Benzyliden-N^α--hydrazinoessigsaeure-aethylester is designed to facilitate the formation of peptide bonds while preventing unwanted side reactions, making it a valuable tool in the synthesis of complex peptide sequences.

Check Digit Verification of cas no

The CAS Registry Mumber 4666-68-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,6 and 6 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4666-68:
(6*4)+(5*6)+(4*6)+(3*6)+(2*6)+(1*8)=116
116 % 10 = 6
So 4666-68-6 is a valid CAS Registry Number.
