Check Digit Verification of cas no

The CAS Registry Mumber 20507-33-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,5,0 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 20507-33:
(7*2)+(6*0)+(5*5)+(4*0)+(3*7)+(2*3)+(1*3)=69
69 % 10 = 9
So 20507-33-9 is a valid CAS Registry Number.

Sulfoxide-mediated Umpolung of alkali halide salts

Klimczyk, Sebastian,Huang, Xueliang,Fares, Christophe,Maulide, Nuno

, p. 4327 - 4329 (2012)

A new protocol for the direct two-electron oxidative Umpolung of alkali halide salts is reported. This procedure, relying on the use of a commercially available sulfoxide as the oxidant, allows the electrophilic halogenation of carbonyl compounds as well as halolactonisation reactions to proceed from the corresponding sodium salts, at room temperature and under mild conditions.
