Check Digit Verification of cas no
The CAS Registry Mumber 2845-09-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,4 and 5 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2845-09:
(6*2)+(5*8)+(4*4)+(3*5)+(2*0)+(1*9)=92
92 % 10 = 2
So 2845-09-2 is a valid CAS Registry Number.

Sodium exhibits better efficacy and selectivity than Li and K for converting Ph3P(O) to Ph2P(OM). The destiny of PhNa co-generated is disclosed. A series of alkyl halides R4X and aryl halides ArX all react with Ph2P(ONa) to produce the corresponding phosphine oxides in good to excellent yields.
ALKYLATION IN SITU OF ARYLPHOSPHINES FORMED DURING THERMOLYSIS OF HYDROPHOSPHORYL COMPOUNDS
Chauzov, V. A.,Kostina, L. P.
, p. 2026 - 2031 (2007/10/02)
In the course of the thermolysis (ca. 200 deg C) of diorganophosphonous and phenylphosphonous acids in the presence of alkyl halides, polyalkylation products are obtained - dialkyldiphenyl- and trialkylphenylphosphonium salts and dialkylphenylphosphine oxides.Combined with alkaline splitting of the phosphonium salts, it is possible to synthesize dialkylphenyl- and trioctylphosphine oxides from available hydrophosphoryl compounds using these reactions.
