Check Digit Verification of cas no

The CAS Registry Mumber 495-41-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,9 and 5 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 495-41:
(5*4)+(4*9)+(3*5)+(2*4)+(1*1)=80
80 % 10 = 0
So 495-41-0 is a valid CAS Registry Number.

Solvent responsive self-separation behaviour of Br?nsted acidic ionic liquid-polyoxometalate hybrid catalysts on H2O2 mediated oxidation of alcohols

Kashyap, Niharika,Das, Sukanya,Borah, Ruli

, (2021)

Two solvent responsive self-separative ionic liquid-based POM hybrids [DEDSA]3[PW12O40] and [DEDSA]3[PMo12O40] were prepared by combination of diethyldisulphoammonium chloride [DEDSA]Cl with Keggin phosphotungstic acid and phosphomolybdic acid. Properties like water tolerance, high activity, high thermal stability and reusability in these POM hybrid compounds facilitate a new type of POM based catalysis used for oxidation of organic alcohols using hydrogen peroxide as oxidizing agent. Due to varied solubility of the hybrid with different solvents, the hybrid can effectively catalyze the oxidation reaction in homogenous condition and then can finally switch back to heterogenous system and convert as self-precipitating catalyst on addition of suitable solvent at the end of the reaction, which made the recovery and reuse of the hybrid very convenient. The catalysts are characterized via different analytical and spectroscopic tools like FT-IR, 1H NMR, 13C NMR, 31P NMR, TGA, UV–Visible, Powder XRD techniques, Raman etc. It was found that the prepared material was highly acidic, thermally stable in nature and was recycled up to 7 times without much loss of catalytic activity.

Modular access to 1,2-allenyl ketones based on a photoredox-catalysed radical-polar crossover process

Du, Chan,Fang, Jianghua,Fang, Yewen,Lei, Wan,Li, Yan,Liu, Yongjun

supporting information, p. 8502 - 8506 (2021/10/20)

Herein, a new protocol dealing with the preparation of 1,2-allenyl ketones has been successfully developedviathe reactions of enynes with radicals enabled by dual photoredox/copper catalysis. Based on the results of a deuteration experiment and the competition reaction between cyclopropanation and allenation, the mechanism based on a photoredox-neutral-catalysed radical-polar crossover process has been proposed. Synthetic applications of allenes have also been demonstrated.

Photocatalytic Stoichiometric Oxidant-Free Synthesis of Linear Unsaturated Ketones from 1,2-Disubstituted Cyclopropanols

Laktsevich-Iskryk, Marharyta V.,Krech, Anastasiya V.,Zhabinskii, Vladimir N.,Khripach, Vladimir A.,Hurski, Alaksiej L.

, p. 1077 - 1086 (2020/12/14)

A one-step catalytic oxidant-free synthesis of unsaturated ketones from 1,2-disubstituted cyclopropanols is reported. Previously for this transformation, only two- and three-step protocols have been developed. The reaction proceeds under irradiation with visible light in the presence of catalytic amounts of both an acridinium photocatalyst and a cobaloxime complex. 2-Aryl-substituted cyclopropanols react giving α,β-unsaturated ketones, while dehydrogenative ring opening of 2-alkyl-substituted substrates affords mixtures of α,β- and β,γ-enones. The reaction starts with one-electron oxidation of a cyclopropanol to cyclopropyloxy radical, presumably, by the photoexcited acridinium catalyst. We also found that Co(dmgBF 2) 2(MeCN) 2complex under an air atmosphere and irradiation with blue LEDs or upon heating can serve as a hydroxycyclopropane oxidant.
