857481-22-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 857481-22-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,7,4,8 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 857481-22:
(8*8)+(7*5)+(6*7)+(5*4)+(4*8)+(3*1)+(2*2)+(1*2)=202
202 % 10 = 2
So 857481-22-2 is a valid CAS Registry Number.

Cobalt-catalyzed reductive carboxylation on α,β-unsaturated nitriles with carbon dioxide

Hayashi, Chika,Hayashi, Takuo,Kikuchi, Satoshi,Yamada, Tohru

, p. 565 - 567 (2014)

The reductive carboxylation of α,β-unsaturated carbonyl compounds with carbon dioxide was studied. After the screening of various transition-metal complex catalysts and reducing agents, it was found that the combination of bis(acetylacetonato) cobalt(II)

Cobalt-catalyzed reductive carboxylation of α,β-unsaturated compounds with carbon dioxide

Hayashi, Chika,Hayashi, Takuo,Yamada, Tohru

, p. 862 - 870 (2015/06/25)

The gaseous carbon dioxide incorporation reaction with α,β-unsaturated compounds was examined in the presence of a catalytic amount of bis(acetylacetonato)cobalt(II) and using diethylzinc as a reductant. After screening with various electron-withdrawing g
