Check Digit Verification of cas no

The CAS Registry Mumber 7098-07-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,0,9 and 8 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 7098-07:
(6*7)+(5*0)+(4*9)+(3*8)+(2*0)+(1*7)=109
109 % 10 = 9
So 7098-07-9 is a valid CAS Registry Number.

Solubility of 1-alkyl-3-ethylimidazolium-based ionic liquids in water and 1-octanol

Domanska, Urszula,Rekawek, Anna,Marciniak, Andrzej

, p. 1126 - 1132 (2008)

The liquid-liquid phase equilibria (LLE) of the following imidazolium ionic liquids (ELs), {1-ethyl-3-ethylimidazolium, or 1-butyl-3-ethylimidazolium, or 1-hexyl-3-ethylimidazolium bis{trifluoromethyl)sylfonyl}imide [EEIM][Tf 2N], or [BEIM][Tf2N], or [HEIM][Tf2N], + water or + 1-octanol), and {1-butyl-3-ethylimida-zolium hexafluorophosphate [BEEM][PF6] + water or + 1-octanol}, have been measured. The effect of anion type ([Tf2N]- compared to [PF6]-) and the effect of structural components of an ionic liquid including alkyl chain length on the cation and the ethyl substituent instead of methyl at the cation on the physical-chemical properties of the EL and on the phase behavior were studied. An upper critical solution temperature (UCST) was observed in every system. An increase in me alkyl chain length increases the mutual solubility with 1-octanol and partly with water. Ionic liquids with the ethyl substituent on the cation [HEEM][Tf2N] show higher solubility in 1-octanol in comparison wim the methyl substituent. After the synthesis, the characterization and purity of the compounds were obtained by nuclear magnetic resonance (NMR), elemental analysis, water content (Fischer mediod), and differential scanning microcalorimetry (DSC). From DSC, the melting point, enthalpy of fusion, and the temperatures of glass transition of all the investigated ionic liquids were determined. The experimental LLE data were correlated by means of the NRTL equation.

A solventless route to 1-ethyl-3-methylimidazolium fluoride hydrofluoride, [C2mim][F]·xHF

Rijksen, Christiaan,Rogers, Robin D.

, p. 5582 - 5584 (2008)

(Chemical Equation Presented) The ionic liquid 1-ethyl-3-methylimidazolium fluoride hydrofluoride, [C2mim][F]·xHF, has been synthesized through a new, solventless route that excludes halogen metathesis. The byproducts are salts, alcohols, and carbon dioxide.

On the effects of head-group volume on the adsorption and aggregation of 1-(n-hexadecyl)-3-Cm-imidazolium bromide and chloride surfactants in aqueous solutions

Keppeler, Nicolas,Galgano, Paula D.,da Silva Santos, Soraya,Malek, Naved I.,El Seoud, Omar A.

, (2021/02/09)

The effects of the length of alkyl side chain (Cm) of ionic liquid-based surfactants (ILBSs) on their adsorption at the water/air interface, and aggregation in aqueous solutions were investigated for the series 1-(n-hexadecyl)-3-Cm-imidazolium bromides and chlorides, where Cm = C1-C4 for the bromides, and C1-C5 for the chlorides. These physicochemical properties were calculated from surface tension, conductivity, and fluorescence data. It was found that increasing the length of Cm (i.e., volume of the head group) leads to enhancement of surface activity, increase in the area per surfactant molecule at the water/air interface (Amin) and the degree of counter-ion dissociation (αmic). Our data also indicated that increasing the volume of the head group results in a decrease of the critical micelle concentration (cmc), Gibb's free energy of adsorption and micellization, and microscopic polarity of interfacial water. In order to delineate the effects of the presence of unsaturation in the HG, we included members that carry Cm = vinyl and allyl in the bromide series. The effect of these groups was found to be similar to removing a methylene group from Cm. The dependence of the solubilization of a lipophilic dye (Sudan IV) and a drug (nitrendipine) on the length of Cm was also studied.

N-Alkylation of Imidazoles with Dialkyl and Alkylene Carbonates

Gabov,Khamidullina,Puzyrev,Ezhikova,Kodess,Pestov

, p. 2079 - 2086 (2021/02/09)

Abstract: The reactions of imidazoles with a series of dialkyl and alkylene carbonatesafforded the corresponding N-alkyl- andN-(hydroxyalkyl)imidazoles with highyields. The reactivity of dialkyl carbonates decreases in the series dimethyl> diethyl > dibutyl carbonate. Ethylene carbonate is a more efficientalkylating agent than trimethylene carbonate. The mechanisms of alkylation ofimidazole with dimethyl carbonate and ethylene carbonate were studied by DFTquantum chemical calculations at the B3LYP/6-311++G(d,p) level of theory.
