Check Digit Verification of cas no

The CAS Registry Mumber 1240239-85-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,2,3 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1240239-85:
(9*1)+(8*2)+(7*4)+(6*0)+(5*2)+(4*3)+(3*9)+(2*8)+(1*5)=123
123 % 10 = 3
So 1240239-85-3 is a valid CAS Registry Number.

Domino carbopalladation-carbonylation: Generating quaternary stereocenters while controlling β-hydride elimination

Seashore-Ludlow, Brinton,Somfai, Peter

supporting information; experimental part, p. 3732 - 3735 (2010/11/04)

A domino carbopalladation-carbonylation sequence for substrates possessing β-hydrogens is explored. This allows for the construction of complex architectures with vicinal stereocenters in a concise and rapid fashion via the stereocontrolled formation of two carbon-carbon bonds. An integral aspect of this domino reaction is the ability to control β-hydride elimination of the organopalladium intermediate and instead form the carbonylation product.
