Check Digit Verification of cas no

The CAS Registry Mumber 87872-25-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,8,7 and 2 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 87872-25:
(7*8)+(6*7)+(5*8)+(4*7)+(3*2)+(2*2)+(1*5)=181
181 % 10 = 1
So 87872-25-1 is a valid CAS Registry Number.

A Kinetic and Equilibrium Study of the Hydrolysis of Pyrrolidine Green

Beach, Steven F.,Hepworth, John D.,Mason, Donald,Hallas, Geoffrey

, p. 975 - 978 (1983)

Rate constants and the activation parameters ΔH(excit.) and ΔS(excit.) have been determined for the hydrolysis of Pyrrolidine Green over the pH range 10-11.The equilibria associated with the hydrolysis of the dye have been studied over the pH range 0-10 and a reaction scheme is proposed.Equilibrium studies have been extended in the pH range 6.8-7.8 and the thermodynamic parameters ΔH0 and ΔS0 have been obtained.
