Check Digit Verification of cas no

The CAS Registry Mumber 113478-78-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,4,7 and 8 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 113478-78:
(8*1)+(7*1)+(6*3)+(5*4)+(4*7)+(3*8)+(2*7)+(1*8)=127
127 % 10 = 7
So 113478-78-7 is a valid CAS Registry Number.

α,α-Alkylation-Halogenation and Dihalogenation of Sulfoxonium Ylides. A Direct Preparation of Geminal Difunctionalized Ketones

Gallo, Rafael D. C.,Ahmad, Anees,Metzker, Gustavo,Burtoloso, Antonio C. B.

, p. 16980 - 16984 (2017/11/27)

A one-pot alkylation–halogenation of ketosulfoxonium ylides in the presence of alkyl halides is described. The method furnishes several gem-difunctionalized haloketones (an alkyl and F, Cl, Br, or I) in good yields. Replacing alkyl halides with a mixture of electrophilic halogen species and various halide anions led to gem-dihalogenated ketones containing a combination of the same or two different halogens. Kinetic isotopic effects as well as reaction kinetic experiments give insight to the mechanism of these reactions.
