Check Digit Verification of cas no

The CAS Registry Mumber 68223-61-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,2,2 and 3 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 68223-61:
(7*6)+(6*8)+(5*2)+(4*2)+(3*3)+(2*6)+(1*1)=130
130 % 10 = 0
So 68223-61-0 is a valid CAS Registry Number.

KINETICS OF THE SULFONATION OF AMINES OF THE BENZENE SERIES BY CHLOROSULFONIC ACID

Khelevin, R. N.

, p. 1709 - 1713 (2007/10/02)

The kinetics of the sulfonation of amines of the benzene series by an equimolar amount of chlorosulfonic acid in o-dichlorobenzene were studied.It was shown that the sulfonation of aniline and N-alkylanilines is described by a second-order kinetic equation for irreversible reactions.The sulfonation of N,N-dialkylanilines by chlorosulfonic acid is described by a first-order kinetic equation for irreversible reactions.The observed relationships are explained by different mechanism for the sulfonation of amines of the benzene series by chlorosulfonic acid.The sulfonation of aniline and N-alkalynilines takes place by direct reaction between the unprotonated molecules of the amines and the HSO3(1+) ion, whereas in the reaction of chlorosulfonic acid with N,N-dialkylanilines complexes of the N,N-dialkylanilines with sulfur trioxide (dialkylanilinesulfotrioxides) are formed initially and then rearrange to the corresponding para-aminosulfonic acids.
