Calculate Digit Verification of CAS Registry Number 1143504-31:
(9*1)+(8*1)+(7*4)+(6*3)+(5*5)+(4*0)+(3*4)+(2*3)+(1*1)=107
107 % 10 = 7
So 1143504-31-7 is a valid CAS Registry Number.

Preparation of diphenyl phosphide and substituted phosphines using alkali metal in silica gel (M-SG)

Nandi, Partha,Dye, James L.,Bentley, Philip,Jackson, James E.

supporting information; experimental part, p. 1688 - 1692 (2009/09/06)

Alkali metals absorbed in silica gel (the M-SG reagents) efficiently cleave C-P bonds in triaryl- and diarylphosphines. The resulting alkali metal phosphides can serve as useful building blocks for a variety of phosphines. Alkyldiarylphosphines undergo exclusive aryl group cleavage.
