Check Digit Verification of cas no

The CAS Registry Mumber 501378-42-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,1,3,7 and 8 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 501378-42:
(8*5)+(7*0)+(6*1)+(5*3)+(4*7)+(3*8)+(2*4)+(1*2)=123
123 % 10 = 3
So 501378-42-3 is a valid CAS Registry Number.

Imide-catalyzed oxidation system: Sulfides to sulfoxides and sulfones

Fukuda, Naohiro,Ikemoto, Tomomi

supporting information; experimental part, p. 4629 - 4631 (2010/09/17)

R1SR2 Imide(cat.), → Toulene or DME R 1SOR2 R1SO2R2 A new combination system, the oxidation of sulfides using aqueous NaOCl in the presence of a catalytic amount of imide under two-phase conditions, has been developed. The combination effectively converts various sulfides to the corresponding sulfoxides and sulfones. It was deduced that the imide could react with NaOCl to produce N-chloroimide, which would play roles of both the active oxidizing reagent and phase transfer catalyst.
