Check Digit Verification of cas no

The CAS Registry Mumber 7205-85-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,0 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7205-85:
(6*7)+(5*2)+(4*0)+(3*5)+(2*8)+(1*5)=88
88 % 10 = 8
So 7205-85-8 is a valid CAS Registry Number.

1,4-Bis(alkylsulfonyl)benzenes. A new and unexpected cathodic cleavage leading to the corresponding phenoxy ions

Simonet, Jacques,Fourets, Olivier,Pilard, Jean-Fran?ois

, p. 1763 - 1765 (2007/10/03)

1,4-Bis(alkylsulfonyl)benzenes 2 exhibit the formation of a fairly stable anion radical under cathodic electron transfer. Its fragmentation leads both to 1-alkylsulfonyl-4-alkyl benzenes (ipso substitution) and 4- alkylsulfonylphenoxy ions, the presence of the latter suggesting a new mode of cleavage for strongly activated sulfones.
