Check Digit Verification of cas no

The CAS Registry Mumber 21245-08-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,4 and 5 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 21245-08:
(7*2)+(6*1)+(5*2)+(4*4)+(3*5)+(2*0)+(1*8)=69
69 % 10 = 9
So 21245-08-9 is a valid CAS Registry Number.

SYNTHESE ET STRUCTURE D'OXYDES ET DIOXYDES DE PHOSPHINES TERTIAIRES

Platzer, Nicole,Dardoise, Francois,Bergeret, Wilfrid,Gautier, Jean Claude,Raynal, Serge

, p. 275 - 284 (2007/10/02)

Tertiary phosphine oxides have been prepared in excellent yield from primary alkyl halides and dihalides or aromatic halides and activated sodium phosphinates obtained by reaction of dialkyl phosphine oxides with complex bases (NaNH2/tBuONa).We have studied by 13C NMR the structure of these compounds.We have reported more particularly the influence of carbon atoms number between the two phosphorus in the case of dioxides and the influence of some parameters such as the temperature and the solvent on the NMR spectra.
