Check Digit Verification of cas no

The CAS Registry Mumber 6294-34-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,9 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 6294-34:
(6*6)+(5*2)+(4*9)+(3*4)+(2*3)+(1*4)=104
104 % 10 = 4
So 6294-34-4 is a valid CAS Registry Number.

Reaction of di-2-chloroethyl 2-chloroethanephosphonate with potassium methacrylate

Tuzhikov,Khokhlova,Bondarenko,Orlova,Abramova

, p. 738 - 741 (2010)

Reaction of di-2-chloroethyl 2-chloroethanephosphonate with potassium methacrylate at various component ratios was studied with the aim to prepare products containing methacrylate and vinyl functional groups. The structures of the compounds obtained were examined by 1H NMR and IR spectroscopy and by gas chromatography-mass spectrometry.

Optimization of 2-chloroethylphosphonic acid synthesis by acid hydrolysis of dialkyl-2-chloroethylphosphonate compounds. Influence of the nature of alkyl phosphonate functions

Cauret, Laurent,Brosse, Jean-Claude,Derouet, Daniel,Livonniere, Hugues De

, p. 463 - 470 (2007/10/03)

2-Chloroethylphosphonic acid (ethephon) 1 is very much used in agriculture as a plant regulator.It is an especially good stimulant used to increase the latex production of Hevea brasiliensis.Ethephon is generally obtained by HCl hydrolysis of bis(2-chloroethyl)-2-chloroethylphosphonate, previously prepared by Arbuzov rearrangement of tri(2-chloroethyl)phosphite.However, because of the low reactivity of 2-chloroethylphosphonate functions towards acid hydrolysis, this synthetic way is not convenient to prepare pure 2-chloroethylphosphonic acid with high yields.The present purpose was to study the hydrolysis of various dialkyl-2-chloroethylphosphonates in view to define an efficient synthetic protocol, leading to very pure crystallized ethephon with high yields. - Keywords: 2-chloroethylphosphonic acid; ethephon; dialkyl-2-chloroethylphosphonate; Arbuzov reaction; trialkyl phosphite; acid hydrolysis

Process for the manufacture of 2-chloroethane-phosphonic acid

-

, (2008/06/13)

An improved process for the manufacture of 2-chloroethane-phosphonic acid in which 2-chloroethane-phosphonic acid bis(2-chloroethyl) ester is heated with 50 to 500% by weight of aqueous hydrochloric acid at temperatures above 100° C. under pressure, the 1,2-dichloroethane formed during the reaction is continuously or discontinuously distilled off and the decrease in pressure is compensated by adding gaseous hydrogen chloride.
