21851-89-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 21851-89-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,8,5 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 21851-89:
(7*2)+(6*1)+(5*8)+(4*5)+(3*1)+(2*8)+(1*9)=108
108 % 10 = 8
So 21851-89-8 is a valid CAS Registry Number.

Facile and general synthesis of polyphosphane polyoxides with (O)PCP(O) linkages

Cristau, Henri-Jean,Virieux, David,Mouchet, Patrick,Fruchier, Alain

, p. 1561 - 1569 (2007/10/03)

Polyphosphane polyoxides with (O)PCP(O) linkages are powerful chelating agents for extraction of actinides from nuclear wastes. They are obtained either by the Michaelis-Arbuzov reaction of chloromethylphosphane oxides and phosphorus(III) esters, or by the reaction of phosphane oxide carbanions with chlorophosphanes. With the latter method, the addition of a phosphane oxide carbanion in excess allowed us to overcome a transmetallation reaction and thereby obtain polyphosphane polyoxides in good yields. The 1H-NMR spectra of the PCH2P groups show the influence of the different R groups attached to the phosphorus atoms. We determined the coupling constants and the chemical shifts of these spin systems.
