Check Digit Verification of cas no

The CAS Registry Mumber 1202745-32-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,2,7,4 and 5 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1202745-32:
(9*1)+(8*2)+(7*0)+(6*2)+(5*7)+(4*4)+(3*5)+(2*3)+(1*2)=111
111 % 10 = 1
So 1202745-32-1 is a valid CAS Registry Number.

One-pot vinylation of secondary phosphine chalcogenides with vinyl sulfoxides

Malysheva, Svetlana F.,Gusarova, Nina K.,Belogorlova, Natal'Ya A.,Kashik, Tamara V.,Krivdin, Leonid B.,Fedorov, Sergei V.,Trofimov, Boris A.

, p. 1838 - 1844 (2010)

A facile, one-pot vinylation of secondary phosphine chalcogenides with alkyl(or aryl) vinyl sulfoxides has been elaborated. The vinylation comprises the nucleophilic addition of secondary phosphine chalcogenides to the vinyl sulfoxides (50 mol% KOH, dioxa
