5032-95-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5032-95-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,3 and 2 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5032-95:
(6*5)+(5*0)+(4*3)+(3*2)+(2*9)+(1*5)=71
71 % 10 = 1
So 5032-95-1 is a valid CAS Registry Number.

Synthesis and characterization of some perfluorophenylphosphine derivatives

Magnelli,Tesi,Lowe Jr.,Mcquistion

, p. 457 - 461 (2008/10/08)

Bis(pentafluorophenyl)chlorophosphine and pentafluorophenyldichlorophosphine are prepared in good yields from pentafluorophenylmagnesium bromide and phosphorus trichloride. The reactions of the halophosphines with the Lewis bases water, ammonia, dimethylamine, and 2-methylaziridine produced substituted phosphines. Oxidative chlorination of bis(pentafluorophenyl)phosphinamide followed by dehydrohalogenation gave perfluorophenylphosphonitriles. The infrared and pertinent proton magnetic resonance spectra of these compounds are discussed.
