Check Digit Verification of cas no

The CAS Registry Mumber 73475-35-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,4,7 and 5 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 73475-35:
(7*7)+(6*3)+(5*4)+(4*7)+(3*5)+(2*3)+(1*5)=141
141 % 10 = 1
So 73475-35-1 is a valid CAS Registry Number.

Enhancement of the Equilibrium Acidities of Carbon Acid by Polyfluoroaryl Substituents

Bordwell, F. G.,Branca, John C.,Bares, Joseph E.,Filler, Robert

, p. 780 - 782 (1988)

Acidity measurements in Me2SO solution have revealed that C6F5CH2CN is 5.9 pKa units more acidic than C6H5CH2CN due to the large field/ inductive effects of the five fluorine atoms.Smaller C6X5 substituent differences (ΔpKa) were obs
