Z-Glu(NH2)-O-o-nitrophenylester, also known as Z-Glutamic acid o-nitrophenyl ester, is a synthetic chemical compound that serves as a substrate for certain enzymes, particularly peptidases and proteases. The compound is characterized by a glutamic acid residue with a carboxyl group protected by a benzyloxycarbonyl (Z) group, an amino group (NH2), and an o-nitrophenyl ester group. This structure allows for the study of enzyme kinetics and mechanism, as the o-nitrophenol group changes color upon hydrolysis, providing a colorimetric assay for enzyme activity. The compound is widely used in biochemical research to assess the catalytic efficiency and specificity of enzymes involved in peptide bond cleavage.

Check Digit Verification of cas no

The CAS Registry Mumber 49689-67-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,6,8 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 49689-67:
(7*4)+(6*9)+(5*6)+(4*8)+(3*9)+(2*6)+(1*7)=190
190 % 10 = 0
So 49689-67-0 is a valid CAS Registry Number.
