955139-40-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 955139-40-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,5,1,3 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 955139-40:
(8*9)+(7*5)+(6*5)+(5*1)+(4*3)+(3*9)+(2*4)+(1*0)=189
189 % 10 = 9
So 955139-40-9 is a valid CAS Registry Number.

Homolytic substitution at phosphorus for the synthesis of alkyl and aryl phosphanes

Vaillard, Santiago E.,Mueck-Lichtenfeld, Christian,Grimme, Stefan,Studer, Armido

, p. 6533 - 6536 (2007)

(Chemical Equation Presented) A transition-metal-free radical phosphonation using Me3SnPPh2 and the less toxic Me 3SiPPh2 is reported. These readily available reagents react highly efficiently with primary and secondary alkyl radicals. Moreover, aryl radicals and tertiary alkyl radicals are phosphonated with Me 3SnPPh2 (see scheme; R = aryl, alkyl, vinyl; X = 1, Br, OC(S)imidazolyl). DFT calculations provide insights into the mechanism of the reaction.
