Check Digit Verification of cas no

The CAS Registry Mumber 1042728-33-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,2,7,2 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1042728-33:
(9*1)+(8*0)+(7*4)+(6*2)+(5*7)+(4*2)+(3*8)+(2*3)+(1*3)=125
125 % 10 = 5
So 1042728-33-5 is a valid CAS Registry Number.

Catalytic amide-mediated methyl transfer from silanes to alkenes in Fujiwara-Moritani oxidative coupling

Rauf, Waqar,Brown, John M.

supporting information; experimental part, p. 4228 - 4230 (2009/03/12)

(Chemical Equation Presented) Intramolecular assistance: Carbon-bound trimethylsilyl groups are activated intramolecularly by a carbonyl group and can participate in Heck reactions under oxidative conditions. Good stereoselectivities are obtained for a range of di-and trisubstituted alkenes (see example).
