Check Digit Verification of cas no

The CAS Registry Mumber 31709-15-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,7,0 and 9 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 31709-15:
(7*3)+(6*1)+(5*7)+(4*0)+(3*9)+(2*1)+(1*5)=96
96 % 10 = 6
So 31709-15-6 is a valid CAS Registry Number.

The apparent pseudo-first-order rate constants for the title reaction give a curvilinear plot versus tertiary amine concentration, according to the equation kA=(ku+K1k2)/(1+K1).This shows the occurrence of two different reaction pathways; the one, independent of and the other, dependent on , which involves a fast conversion of the substrate into an acid-base adduct or an ion pair followed by its slow conversion into the corresponding triazole.The substituent effects on these reactions have also been studied.
