21160-82-7 Usage
General Description
Z-LYS(Z)-ONP is a chemical compound consisting of the amino acid lysine (Lys) linked to the protecting group Z and the chromogenic p-nitroanilide (ONP). Z-LYS(Z)-ONP is commonly used in biochemical and pharmaceutical research as a substrate for protease enzymes, particularly trypsin-like serine proteases. Upon cleavage by the protease enzyme, Z-LYS(Z)-ONP releases the yellow p-nitroaniline (pNA) chromophore, allowing for easy detection and quantification of protease activity. The Z protecting group is used to prevent unwanted cleavage of the peptide bond prior to reaction with the protease. Z-LYS(Z)-ONP is an important tool in the study of protease kinetics, inhibitor screening, and drug development.
Check Digit Verification of cas no
The CAS Registry Mumber 21160-82-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,1,6 and 0 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 21160-82:
(7*2)+(6*1)+(5*1)+(4*6)+(3*0)+(2*8)+(1*2)=67
67 % 10 = 7
So 21160-82-7 is a valid CAS Registry Number.
