Check Digit Verification of cas no

The CAS Registry Mumber 1043-55-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,4 and 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1043-55:
(6*1)+(5*0)+(4*4)+(3*3)+(2*5)+(1*5)=46
46 % 10 = 6
So 1043-55-6 is a valid CAS Registry Number.

The oxidation of the bridging sulfur atom in diphenyl sulfides, leading to the formation of sulfoxides and sulfones, was investigated.The various rearrangement processes which occur in substituted 2,4-dinitrophenyl phenyl sulfoxides during electron impact and lead to the appearance of characteristic fragment ions were demonstrated.The effect of the nature of substituents on the main directions in mass-spectrometric dissociation was investigated, and a correlation was obtained between log Z'/Z for the fragment due to elimination of the bridging SO group from the molecular ion and the Hammett ? constants.
