4546-11-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4546-11-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,4 and 6 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4546-11:
(6*4)+(5*5)+(4*4)+(3*6)+(2*1)+(1*1)=86
86 % 10 = 6
So 4546-11-6 is a valid CAS Registry Number.

Surface mediated synthesis of unsymmetrical O,O-dialkyl alkyl pyrophosphonates using neutral alumina: potential Chemical Weapons Convention related compounds

Kumar, Rajesh,Dubey, Devendra. K.,Gupta, Arvind. K.,Kaushik

, p. 273 - 277 (2008)

The surface mediated synthesis of unsymmetrical O,O'- dialkyl alkyl pyrophosphonates from O-alkyl alkylphosphonic acid is described. These pyrophosphonates are listed in schedule 2B4 of Chemical Weapon Convention (CWC). The effect of the presence of chromatographic grade of AI2O 3 on the phosphorylation of a series of alkyl phosphonic acids has also been investigated. For phosphonic acids having different alkyl groups, it was observed that higher yields of the more hindered pyrophosphonates were formed in the presence of AI2O3. This method has an advantage over the conventional methods in terms of easy work-up, reduced reaction time and high yields.

DCC-Celite hybrid immobilized solid support as a new, highly efficient reagent for the synthesis of O-alkyl hydrogen alkylphosphonates under solvent-free conditions

Gupta,Kumar, Rajesh,Gupta,Tak, Vijay,Dubey

, p. 1656 - 1659 (2008/09/18)

An efficient and solvent-free synthesis of O-alkyl hydrogen alkyl phosphonates is described. The methodology involves the condensation of alkyl phosphonic acids using DCC-Celite under solvent-free conditions.

Preparation, derivatization with trimethylsilyldiazomethane, and GC/MS analysis of a "pool" of alkyl methylphosphonic acids for use as qualitative standards in support of counterterrorism and the chemical weapons convention

Crenshaw, Michael D.,Cummings, David B.

, p. 1009 - 1018 (2007/10/03)

There are hundreds of nerve agents in the class of alkyl methylphosphonofluoridates covered by Schedule 1 of the CWC (Chemical Weapons Convention). Hydrolysis of these sarin-like nerve agents results in an equal number of alkyl methylphosphonic acids. These alkyl methylphosphonic acids are persistent and provide good evidence of specific agent production or use. In order to support the CWC and counterterrorism activities, it is desirable to have ready access to each of these hydrolysis products for use as qualitative standards. A means for simultaneously producing multiple alkyl methylphosphonates from methylphosphonic acid and the corresponding alcohols was developed. Derivatization of these alkyl methylphosphonic acids with trimethylsilyldiazomethane yields the corresponding methyl esters which are suitable for GC/MS analysis.
