102-66-9 Usage
General Description
Aspartic acid-beta-p-nitroanilide, also known as Aspartyl-p-nitroanilide or Aspartic acid-β-(4-nitroanilide), is a chemical compound used in biochemical and enzymatic assays. It is commonly employed as a substrate for various enzymes, particularly proteases and amidases, in biochemical research and diagnostics. When cleaved by these enzymes, it produces a p-nitroaniline product, which can be quantified spectrophotometrically due to its characteristic absorbance at a specific wavelength.
Check Digit Verification of cas no
The CAS Registry Mumber 102-66-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,0 and 2 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 102-66:
(5*1)+(4*0)+(3*2)+(2*6)+(1*6)=29
29 % 10 = 9
So 102-66-9 is a valid CAS Registry Number.
