Check Digit Verification of cas no

The CAS Registry Mumber 474383-40-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,4,3,8 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 474383-40:
(8*4)+(7*7)+(6*4)+(5*3)+(4*8)+(3*3)+(2*4)+(1*0)=169
169 % 10 = 9
So 474383-40-9 is a valid CAS Registry Number.

Radical β-elimination of a sulfinyl group to afford allenes

Mouries, Virginie,Delouvrie, Benedicte,Lacote, Emmanuel,Fensterbank, Louis,Malacria, Max

, p. 1776 - 1787 (2007/10/03)

An unprecedented radical β-elimination of vinyl sulfoxides has opened a new route to functionalized allenes. The radical precursors were obtained in two steps from a carbonyl derivative and a vinyl sulfoxide. The radical translocation stratagem could also be used to trigger the β-elimination of the sulfinyl radical. Variation of the nature of the sulfur group on a common precursor gave no allene with the thio, sulfonyl, and iminosulfinyl moieties, in contrast to the analogous vinyl sulfoxide and vinylsulfimide precursors.
