40438-59-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 40438-59-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,4,3 and 8 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 40438-59:
(7*4)+(6*0)+(5*4)+(4*3)+(3*8)+(2*5)+(1*9)=103
103 % 10 = 3
So 40438-59-3 is a valid CAS Registry Number.

Arenediazonium tetrafluoroborates in palladium-catalyzed C-P bond-forming reactions. Synthesis of arylphosphonates, -phosphine oxides, and -phosphines

Berrino, Roberta,Cacchi, Sandro,Fabrizi, Giancarlo,Goggiamani, Antonella,Stabile, Paolo

supporting information; experimental part, p. 4518 - 4520 (2010/11/17)

A novel palladium-catalyzed synthesis of arylphosphonates from arenediazonium tetrafluoroborates and triethylphosphite or diethylphosphite is presented. The reaction tolerates useful substituents including bromo, chloro, nitro, ether, cyano, keto, and ester groups, can be performed as a one-pot process from anilines omitting the isolation of arenediazonium salts, and can be extended to the preparation of arylphosphine oxides and arylphosphines.
