Check Digit Verification of cas no

The CAS Registry Mumber 521304-36-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,2,1,3,0 and 4 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 521304-36:
(8*5)+(7*2)+(6*1)+(5*3)+(4*0)+(3*4)+(2*3)+(1*6)=99
99 % 10 = 9

A simple halide-to-anion exchange method for heteroaromatic salts and ionic liquids

Alcalde, Ermitas,Dinares, Immaculada,Ibanez, Anna,Mesquida, Neus

experimental part, p. 4007 - 4027 (2012/07/28)

A broad and simple method permitted halide ions in quaternary heteroaromatic and ammonium salts to be exchanged for a variety of anions using an anion exchange resin (A- form) in non-aqueous media. The anion loading of the AER (OH- form) was examined using two different anion sources, acids or ammonium salts, and changing the polarity of the solvents. The AER (A- form) method in organic solvents was then applied to several quaternary heteroaromatic salts and ILs, and the anion exchange proceeded in excellent to quantitative yields, concomitantly removing halide impurities. Relying on the hydrophobicity of the targeted ion pair for the counteranion swap, organic solvents with variable polarity were used, such as CH3OH, CH3CN and the dipolar nonhydroxylic solvent mixture CH3CN:CH2Cl 2 (3:7) and the anion exchange was equally successful with both lipophilic cations and anions.

PROBLEM: Providing a novel ionic liquid, which is low-cost, environment-friendly, and has low viscosity and melting point. MEANS FOR SOLVING THE PROBLEM: The present invention is the invention of the ionic liquid represented by the general formula [1]: {wherein, R1 to R3 and n pieces of R4 each independently represent hydrogen atom or alkyl group having 1 to 4 carbon atoms, R5 to R7 each independently represent alkyl group, aralkyl group, or aryl group, R8 represents alkyl group, aralkyl group, aryl group, or the one represented by the general formula [2]: (wherein T represents alkylene chain having 1 to 8 carbon atoms, n represents 1 or 2, and R1 to R7 are the same as the above-described), X represents nitrogen atom or phosphorus atom, n represents 1 or 2. When n is 1, R3 and R4 are bound and may form cyclohexene ring together with the adjacent carbon atoms. In addition, when X is nitrogen atom, R5 to R7 or R5 to R6 may form hetero ring with nitrogen atom binding thereto}.

Imidazolium ionic liquids: A simple anion exchange protocol

supporting information; experimental part, p. 1507 - 1510 (2010/06/11)

An efficient and simple protocol was developed to obtain quantitative iodide or bromide exchange for a broad range of anions in imidazolium ionic liquids. Selected anions were loaded in an anion exchange resin using two different procedures and were then used to provide a pure convenient ion pair. The Royal Society of Chemistry 2009.

experimental part, p. 8939 - 8948 (2010/06/20)

A set of 1-alkyl-3-methylimidazolium alkanesulfonate ionic liquids, [C nmim][CkSO3], formed by the variation of the alkyl chain lengths both in the cation and the anion (n = 1-6, 8, or 10; k = 1-4, or 6), was synthesised, with sixteen of them being novel. The ionic liquids were characterised by 1H and 13C NMR spectroscopy, and mass spectrometry. Their viscosities and densities as a function of temperature, as well as melting points and decomposition temperatures, were determined. The molecular volumes, both experimental and calculated, were found to depend linearly on the sum (n + k). the Owner Societies 2009.

Method of preparation of halogen-free ionic liquids and ionic liquids prepared in this manner

-

Page/Page column 3-4, (2008/06/13)

The reaction of N-alkylimidazol with alkyl sulfonates, at room temperature, favors the production of 1,3-dialkylimidazolium alkane-sulfonates as crystalline solids at high yields. The alkane-sulfonate anions may be easily substituted by a series of other anions [BF4, PF6, PF3(CF2CF3)3, CF3SO3 and (CF3SO2)2N] through simple anion, salt, or acid reactions in water at room temperature. The extraction with dichloromethane, filtration, and evaporation of the solvent, allows the production of the desired ionic liquids at a yield of 80-95%. The purity of these ionic liquids (in some cases >99.4%) is performed using the intensity of 13C satellite signals from the magnetic resonance spectrums of the N-methyl imidazolium group as an internal standard.

A simple and practical method for the preparation and purity determination of halide-free imidazolium ionic liquids

Cassol, Claudia C.,Ebeling, Guenter,Ferrera, Bauer,Dupont, Jairton

, p. 243 - 248 (2007/10/03)

The reaction of N-alkylimidazole with alkyl sulfonates at room temperature affords 1,3-dialkylimidazolium alkanesulfonates as crystalline solids in high yields. The alkanesulfonate anions can be easily substituted by a series of other anions [BF4, PF6, PF3(CF 2CF3)3, CF3SO3 and N(CF3SO2)2] by simple reaction of anions, salts, or acids in water at room temperature. Extraction with dichloromethane, filtration through a short basic alumina column and solvent evaporation affords the desired ionic liquids in 80-95% yield. The purity (> 99.4%) of these ionic liquids can be determined by 1H NMR spectra using the intensity of the 13C satellites of the imidazolium N-methyl group as internal standard.

Ionic liquids as reaction media for esterification of carboxylate sodium salts with alkyl halides

Brinchi,Germani,Savelli

, p. 2027 - 2029 (2007/10/03)

Ionic liquids based on 1,3-dialkylimidazolinium methanesulfonate have been used as effective reusable reaction media in the esterification of several carboxylate sodium salts with different alkyl halides. Products are easily isolated by extraction with ether, and the protocol is mild and green, compared to the existing methods based on toxic solvents. Proper 'design' of the ionic liquid allows us to obtain esters always in quantitative yields.
