Check Digit Verification of cas no
The CAS Registry Mumber 81-10-7 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 1 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 81-10:
(4*8)+(3*1)+(2*1)+(1*0)=37
37 % 10 = 7
So 81-10-7 is a valid CAS Registry Number.

Conversion of o-Nitrothiophenols into o-Aminobenzenesulphonic Acids
Bamfield, Peter,Greenwood, David,Lotey, Harvinder,Stirling, Charles J. M.
, p. 691 - 696 (2007/10/02)
The mechanism of conversion of o-nitrothiophenols into o-aminobenzenesulphonic acids in aqueous dioxane has been investigated with particular reference to evidence for the rate-determining formation of a cyclic intermediate.This intermediate is susceptible to interception by both external and internal nucleophilic functions, and the sulphonic acid is shown by isotope labelling experiments to take two oxygen atoms from H2(18)O in the reaction mixture, under conditons in which neither starting materials nor products exchange with H2(18)O.A tentative pathway is advanced.
