Tritylsulfenyl-Phe-ONP, also known as 9-fluorenylmethyloxycarbonyl-L-phenylalanine p-nitrophenyl ester, is a synthetic chemical compound that serves as a substrate for the enzyme chymotrypsin. It is a derivative of the amino acid phenylalanine, with a tritylsulfenyl group attached to the nitrogen atom and a p-nitrophenol (ONP) group attached to the carboxyl group. Tritylsulfenyl-Phe-ONP is widely used in biochemical research to study the activity and specificity of chymotrypsin and other serine proteases. Upon enzymatic hydrolysis, Tritylsulfenyl-Phe-ONP releases p-nitrophenol, which can be easily quantified by measuring the absorbance at 410 nm, allowing for the determination of enzyme kinetics and activity.

Check Digit Verification of cas no

The CAS Registry Mumber 96980-05-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,6,9,8 and 0 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 96980-05:
(7*9)+(6*6)+(5*9)+(4*8)+(3*0)+(2*0)+(1*5)=181
181 % 10 = 1
So 96980-05-1 is a valid CAS Registry Number.
