122630-72-2 Usage
General Description
H-D-Leu-Thr-Arg-pNA is a chemical compound consisting of the amino acids D-leucine, threonine, and arginine, as well as p-nitroaniline (pNA). H-D-Leu-Thr-Arg-pNA is commonly used as a substrate for protease enzymes in biochemical and molecular biology research. When the protease enzyme cleaves the peptide bond between arginine and pNA, it releases pNA, which can be detected spectrophotometrically at 405 nm. This allows for the measurement of protease activity, making H-D-Leu-Thr-Arg-pNA a valuable tool for studying protease kinetics and inhibitor screening.
Check Digit Verification of cas no
The CAS Registry Mumber 122630-72-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,6,3 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 122630-72:
(8*1)+(7*2)+(6*2)+(5*6)+(4*3)+(3*0)+(2*7)+(1*2)=92
92 % 10 = 2
So 122630-72-2 is a valid CAS Registry Number.
