Z-Lys(Boc)-O-o-nitrophenylester is a synthetic chemical compound that serves as a substrate for protease enzymes, particularly useful in the study and characterization of proteolytic activity. The compound is composed of a lysine residue, which is a naturally occurring amino acid, with a benzyloxycarbonyl (Z) protecting group and a Boc (tert-butoxycarbonyl) protecting group. The o-nitrophenylester group is attached to the lysine, making it a chromogenic substrate that changes color upon proteolytic cleavage. This color change allows for the quantification and monitoring of enzyme activity. The compound is widely used in biochemical research and drug discovery to assess the potency and specificity of protease inhibitors, as well as to study enzyme kinetics and mechanisms.

Check Digit Verification of cas no

The CAS Registry Mumber 49689-71-6 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, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 49689-71:
(7*4)+(6*9)+(5*6)+(4*8)+(3*9)+(2*7)+(1*1)=186
186 % 10 = 6
So 49689-71-6 is a valid CAS Registry Number.
