Check Digit Verification of cas no

The CAS Registry Mumber 1431294-81-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,1,2,9 and 4 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1431294-81:
(9*1)+(8*4)+(7*3)+(6*1)+(5*2)+(4*9)+(3*4)+(2*8)+(1*1)=143
143 % 10 = 3
So 1431294-81-3 is a valid CAS Registry Number.

Palladium-catalyzed formal hydroacylation of allenes employing carboxylic anhydrides and hydrosilanes

Fujihara, Tetsuaki,Hosomi, Takuro,Cong, Cong,Hosoki, Tomoya,Terao, Jun,Tsuji, Yasushi

supporting information, p. 4570 - 4574 (2015/03/30)

The formal hydroacylation reaction of allenes has been developed employing carboxylic anhydrides as acyl sources and hydrosilanes as reducing reagents in the presence of a commercially available palladium complex as a catalyst. The reaction affords α,β-unsaturated ketones regio- and stereoselectively. The similar catalyst system is also effective for the reduction of carboxylic anhydrides to the corresponding aldehydes employing hydrosilanes.
