Check Digit Verification of cas no

The CAS Registry Mumber 2168-93-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,6 and 8 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2168-93:
(6*2)+(5*1)+(4*6)+(3*8)+(2*9)+(1*3)=86
86 % 10 = 6
So 2168-93-6 is a valid CAS Registry Number.

Switching the activity of a photoredox catalyst through reversible encapsulation and release

Bianchini, Giulio,Scarso, Alessandro,Sorella, Giorgio La,Strukul, Giorgio

, p. 12082 - 12084 (2012)

Reversible encapsulation of [Ru(bpy)3]2+ within a self-assembled hexameric resorcin[4]arene capsule turns off the photocatalytic aerobic oxidation of an aliphatic sulfide. Upon addition of a competitive cationic guest, the Ru(ii) catalyst is released into solution where its catalytic activity is restored.

Reactions in clay media: Photooxidation of sulfides by clay-bound methylene blue

Madhavan,Pitchumani

, p. 8391 - 8394 (2001)

Photooxidation of dialkyl and alkyl aryl sulfides to the corresponding sulfoxides with clay-bound methylene blue is studied in acetonitrile. A significant increase in sulfoxide/sulfone ratio and a marginal increase in cooxidation of a second sulfide molecule are observed. The results are explained in terms of a suitable mechanism involving persulfoxide and thiadioxirane intermediates.

A Kinetic Study of Sulfide Oxidation by Sodium Hypochlorite Using Phase-Transfer Catalysis

Ramsden, James H.,Drago, Russell S.,Riley, Richard

, p. 3958 - 3961 (1989)

The use of sodium hypochlorite as a synthetically useful oxidizing agent is reported for the oxidation of lipophilic organic sulfide substrates employing phase-transfer catalysis (PTC).The PTC results in nearly complete oxidation of the substrate in 20 min, with high selectivity to the sulfoxide, compared to 5 h in its absence.Kinetic studies show the reaction occur via transfer of OCl- into the organic phase.Under certain conditions the transfer is rate limiting.The addition of a transition-metal catalyst (TPPMnCl) further increased the rate and led to the complete conversion of the sulfide to the sulfone, illustrating that NaOCl(aq) is a potent oxidizing agent in these biphasic systems.

A mild and chemoselective CALB biocatalysed synthesis of sulfoxides exploiting the dual role of AcOEt as solvent and reagent

Anselmi, Silvia,Liu, Siyu,Kim, Seong-Heun,Barry, Sarah M.,Moody, Thomas S.,Castagnolo, Daniele

supporting information, p. 156 - 161 (2021/01/14)

A mild, chemoselective and sustainable biocatalysed synthesis of sulfoxides has been developed exploiting CALB and using AcOEt with a dual role of more environmentally friendly reaction solvent and enzyme substrate. A series of sulfoxides, including the drug omeprazole, have been synthesised in high yields and with excellent E-factors.

Fe(III)-salen complex supported on dendrimer functionalized magnetite nanoparticles as a highly active and selective catalyst for the green oxidation of sulfides

Asadi, Zahra,Masteri-Farahani, Majid,Niakan, Mahsa

, (2020/07/23)

In this study, we reported the preparation of polyamidoamine-modified magnetite nanoparticles and their use for the immobilization of Fe(III)-salen complex to form a novel magnetic catalyst. The prepared catalyst was characterized by some modern techniques i.e. Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), N2 adsorption-desorption analysis, X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDX), X-ray photoelectron spectroscopy (XPS), vibrating sample magnetometry (VSM), and inductively couple plasma atomic emission spectroscopy (ICP-AES). The catalyst showed excellent activity and selectivity for the oxidation of sulfides to sulfoxides (conversion 87–100percent, selectivity 82–100percent) using H2O2 (30percent w/w) as oxidant in aqueous medium at 50 °C. Furthermore, the catalyst could be recovered in a facile manner from the reaction mixture by using a magnet and reused for five cycles with high catalytic stability.

An isotetramolybdate-supported rhenium carbonyl derivative: Synthesis, characterization, and use as a catalyst for sulfoxidation

Lu, Jingkun,Ma, Xinyi,Singh, Vikram,Zhang, Yujiao,Ma, Pengtao,Zhang, Chao,Niu, Jingyang,Wang, Jingping

, p. 5279 - 5285 (2018/04/23)

A novel isotetramolybdate-supported rhenium carbonyl derivative, [(CH3)4N]4[{Re(CO)3}4(Mo4O16)]·H2O (1), has been successfully synthesized and characterized by single crystal X-ray diffraction crystallography, IR and UV spectroscopy, etc. Results showed that, compound 1 is an efficient catalyst for the oxidation of thioanisole into the corresponding sulfoxide in the presence of hydrogen peroxide with good to excellent conversion (99%) and excellent selectivity (93%). Highly efficient oxygenation of thioanisole can also be achieved with 100% selectivity of sulfone and >99% conversion. Furthermore, optimized conditions were applied to a range of sulfides to obtain the corresponding sulfoxides and sulfones.
