Check Digit Verification of cas no

The CAS Registry Mumber 76443-14-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,4,4 and 3 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 76443-14:
(7*7)+(6*6)+(5*4)+(4*4)+(3*3)+(2*1)+(1*4)=136
136 % 10 = 6
So 76443-14-6 is a valid CAS Registry Number.

REACTION OF ALKYL ARENESULFONATES WITH LIQUID SULFUR TRIOXIDE AND AROMATIC HYDROCARBONS

Moskvichev, Yu. A.,Shapiro, Yu E.,Kramerova, S. K.,Sizyk, L. A.,Shutova, I.V.,et al.

, p. 284 - 289 (2007/10/02)

The reaction of sulfur trioxide with methyl 4-toluenesulfonate leads to the formation of p-CH3C6H4SO2(OSO2)nOCH3 (n=1,2) compounds.Investigation of the composition of the products from the reaction of this mixture with aromatic hydrocarbons showed that the diaryl sulfones in this case are formed by a pyrosulfonate mechanism.The optimum conditions for the synthesis of diaryl sulfones were selected.
