Check Digit Verification of cas no

The CAS Registry Mumber 405-31-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,0 and 5 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 405-31:
(5*4)+(4*0)+(3*5)+(2*3)+(1*1)=42
42 % 10 = 2
So 405-31-2 is a valid CAS Registry Number.

Cobalt-iron magnetic composites as heterogeneous catalysts for the aerobic oxidation of thiols under alkali free conditions

Menini, Luciano,Pereira, Márcio C.,Ferreira, André C.,Fabris, José D.,Gusevskaya, Elena V.

, p. 151 - 157 (2011)

Cobalt-iron magnetic composites prepared by the thermal treatment of an iron oxide-rich soil in the presence of sucrose and cobalt(II) sulfate are efficient heterogeneous catalysts for the liquid-phase aerobic oxidation of thiols into disulfides. The mate

Dimsyl Anion Enables Visible-Light-Promoted Charge Transfer in Cross-Coupling Reactions of Aryl Halides

Pan, Lei,Cooke, Maria Victoria,Spencer, Amara,Laulhé, Sébastien

supporting information, p. 420 - 425 (2021/11/01)

A methodology is reported for visible-light-promoted synthesis of unsymmetrical chalcogenides enabled by dimsyl anion in the absence of transition-metals or photoredox catalysts. The cross-coupling reaction between aryl halides and diaryl dichalcogenides proceeds with electron-rich, electron-poor, and heteroaromatic moieties. Mechanistic investigations using UV-Vis spectroscopy, time-dependent density functional theory (TD-DFT) calculations, and control reactions suggest that dimsyl anion forms an electron-donor-acceptor (EDA) complex capable of absorbing blue light, leading to a charge transfer responsible for generation of aryl radicals from aryl halides. This previously unreported mechanistic pathway may be applied to other light-induced transformations performed in DMSO in the presence of bases and aryl halides.

Preparation method of symmetric disulfide bond-containing compound

-

Paragraph 0020; 0072-0074, (2021/11/21)

The method comprises the following steps: adding a raw material and an oxidant to a reaction bottle containing a solvent; reacting 23W - 85W under the irradiation of 12 - 24h energy-saving lamps; and purifying the reaction product to obtain symmetrical disulfide bond-containing compounds. The raw material is mercaptan or thiophenol. The oxidizing agent is trichlorobromomethane, and the solvent is tetrahydrofuran. The method has the advantages of simple operation, high yield (70 - 90%), wide applicability, cheap and easily available raw materials, and provides a better way for the synthesis and production of symmetrical disulfide bond-containing compounds.
