Check Digit Verification of cas no
The CAS Registry Mumber 6461-99-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,6 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6461-99:
(6*6)+(5*4)+(4*6)+(3*1)+(2*9)+(1*9)=110
110 % 10 = 0
So 6461-99-0 is a valid CAS Registry Number.

Synthesis of symmetrical diaryl sulfone by homocoupling of sodium arylsulfinate
Peng, Yao
, p. 265 - 268 (2014/06/09)
An efficient practical homocoupling reaction of sodium arylsulfinate promoted by Cu(II) is reported whereby symmetrical diaryl sulfone derivatives are obtained with high selectivity and reactivity by intermolecular cross-coupling. This homocoupling reacti
PHASE TRANSFER CONTROLLED SELECTIVE OXIDATION OF DIARYLSULFIDES TO DIARYLSULFOXIDES USING POTASSIUM HYDROGEN PERSULFATE
Evans, T. L.,Grade, M. M.
, p. 1206 - 1216 (2007/10/02)
The use of biphasic reaction conditions and a phase transfer catalyst controls the oxidation reaction of potassium hydrogen persulfate with diarylsulfides yielding predominantly sulfoxides.This is in contrast to the raction in polar solvents where sulfones are the major products.
