Check Digit Verification of cas no

The CAS Registry Mumber 1284293-97-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,4,2,9 and 3 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1284293-97:
(9*1)+(8*2)+(7*8)+(6*4)+(5*2)+(4*9)+(3*3)+(2*9)+(1*7)=185
185 % 10 = 5
So 1284293-97-5 is a valid CAS Registry Number.

Palladium-catalyzed carbocyclization of alkynyl ketones proceeding through a carbopalladation pathway

Chernyak, Natalia,Gorelsky, Serge I.,Gevorgyan, Vladimir

supporting information; experimental part, p. 2342 - 2345 (2011/04/18)

Dig this: 5-exo-dig carbocyclization of 1 into 2 features intramolecular carbopalladation of alkyne with Pd enolate (see scheme). DFT calculations show that the key Pd enolate forms by deprotonation assisted byb PdII acetate. Subsequent intramo
