Check Digit Verification of cas no

The CAS Registry Mumber 80526-82-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,5,2 and 6 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 80526-82:
(7*8)+(6*0)+(5*5)+(4*2)+(3*6)+(2*8)+(1*2)=125
125 % 10 = 5
So 80526-82-5 is a valid CAS Registry Number.

Synthesis of [N(CH3)4]2O 3SOSO2(s) and [N(CH3)4] 2[(O2SO)2SO2]·SO 2(s) Containing (SO4)(SO2)x 2- x = 1, 2, members of a new class of sulfur oxydianions

supporting information, p. 7193 - 7202 (2013/07/26)

One mole equivalent of SO2 reversibly reacts with [N(CH 3)4]2SO4(s) to give [N(CH 3)4]2S2O6(s) (1) containing the [O3SOSO2]2-, shown by Raman and IR to be an isomer of the [O3SSO3]2- dianion. The experimental and calculated (B3PW91/6-311+G(3df)) vibrational spectra are in excellent agreement, and the IR spectrum is similar to that of the isoelectronic O3ClOClO2. Crystals of [N(CH 3)4]2(O2SO)2SO 2·SO2 (2) were isolated from solutions of [N(CH3)4]2SO4 in liquid SO 2. The X-ray structure showed that 2 contained the [(O 2SO)2SO2]2- dianion. The characterized N(CH3)4+ salts 1 and 2 are the first two members of the (SO4)(SO2)x 2- class of sulfur oxydianions analogous to the well-known small cation salts of the SO4(SO3)x2- polysulfates.

Alkylation of ammonium salts catalyzed by imidazolium-based ionic liquid catalysts

Zheng, Zhuo Qun,Wang, Jie,Wu, Ting Hua,Zhou, Xiao Ping

, p. 1095 - 1101 (2008/03/27)

Quaternary ammonium salts were synthesized from ammonium salts and dialkyl carbonates over imidazolium ionic liquid catalysts. The reaction gave almost stoichiometric amounts of the quaternary ammonium salts for halides and nitrates. It was found that the electron-donating property of the alkyl moieties of ammonium cations, the electrophilic nature of the alkyl group of the carbonate, the acidity of the acid that the anion of the ammonium salt corresponds to, and the steric hindrance of the ammonium salts and the dialkyl carbonates are the key factors that influence the yields of quaternary ammonium salts. Strong electron-donating alkyl groups on the nitrogen atom of the ammonium salt, electron-withdrawing groups on the methylene carbon of dialkyl carbonate, and weaker steric hindrance of the starting ammonium salts and dialkyl carbonates favor the alkylation reaction of ammonium salts.

METHOD FOR PRODUCING QUATERNARY AMMONIUM COMPOUNDS

-

Page/Page column 20, (2008/06/13)

The inventive method for producing quaternary ammonium compounds consists in reacting compounds containing an sp3 hybridised nitrogen atom with dialkyl sulphate or trialkyl phosphate and in exposing the thus obtained ammonium compound to an ion-exchange.
