Check Digit Verification of cas no

The CAS Registry Mumber 21646-99-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,6,4 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 21646-99:
(7*2)+(6*1)+(5*6)+(4*4)+(3*6)+(2*9)+(1*9)=111
111 % 10 = 1
So 21646-99-1 is a valid CAS Registry Number.

Reaction of (chloromethyl)phosphonic(-phosphinic) chlorides with silylated protic nucleophiles

Saakyan

, p. 1712 - 1716 (2007/10/03)

Reactions of (chloromethyl)phosphonic(-hosphinic) chlorides with trimethylalkoxy(-phenoxy, -dialkylamino)silanes are accompanied by elimination of trimethylchlorosilane and lead to formation of related substitution products. Reactions of bis(chloromethyl)phosphinic chloride and (chloromethyl)phosphinic dichloride with neutral and hydrogen silyl phosphites were studied. The reactions of bis(chloromethyl)phosphinic chloride with tris(trimethylsilyl)phosphite, diethyl trimethylsilyl phosphite, and bis(trimethylsilyl) hydrogen phosphite yield trimethylsilyl bis(chloromethyl)phosphinate. Similar reactions with (chloromethyl)phosphonic dichloride resulted in isolation of bis(trimethylsilyl) (chloromethyl)phosphonate.

Electrochemical Oxidation of Metal Dialkyl Phosphites and Their Reaction with Halogens

Romakhin,Zagumennov,Nikitin

, p. 1022 - 1026 (2007/10/03)

Electrochemical oxidation of sodium dialkyl phosphites with alkyl radicals of normal structure leads to formation of tetraalkyl pyrophosphites as the main products, while electrochemical oxidation of litium dialkyl phosphites and sodium salts with branched alkyl radicals yields tetraalkyl hypophosphates. The reaction of metal dialkyl phosphites with halogens leads to analogous results.
