Check Digit Verification of cas no

The CAS Registry Mumber 903570-09-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,3,5,7 and 0 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 903570-09:
(8*9)+(7*0)+(6*3)+(5*5)+(4*7)+(3*0)+(2*0)+(1*9)=152
152 % 10 = 2
So 903570-09-2 is a valid CAS Registry Number.

Fe3O4/PEG-SO3H as a heterogeneous and magnetically-recyclable nanocatalyst for the oxidation of sulfides to sulfones or sulfoxides

Mirfakhraei, Saeideh,Hekmati, Malak,Eshbala, Fereshteh Hosseini,Veisi, Hojat

, p. 1757 - 1761 (2018/02/09)

We present below a sulfonated-polyethylene glycol-coated Fe3O4 nanocomposite (Fe3O4/PEG-SO3H) as a greatly effective and ecological nanocatalyst for the selective oxidation of sulfides to sulfoxides or sulfones with brilliant yields under solvent-free conditions by employing 30% hydrogen peroxide as the oxidant. A number of sulfides containing alcohol, ester, and aldehyde functional groups were fruitfully and selectively oxidized without altering the desired characteristics. The magnetic nanocatalyst (Fe3O4/PEG-SO3H) can be conveniently and swiftly retrieved through the utilization of an external magnetic tool and recycled for more than 10 reaction runs without significantly decreasing its catalytic behavior.

A molybdenum based metallomicellar catalyst for controlled and selective sulfoxidation reactions in aqueous medium

Chakravarthy, Rajan Deepan,Ramkumar, Venkatachalam,Chand, Dillip Kumar

, p. 2190 - 2196 (2014/04/17)

A surfactant based molybdenum system that exhibits catalytic activity for sulfoxidation reactions of various organic sulfides in aqueous medium has been developed and comprehensively characterized using IR, XRD, NMR, ESI-MS, DLS and TEM. The catalyst showcases remarkable selectivity for the preparation of both sulfoxides and sulfones in the range of good to excellent yields. Furthermore, the catalyst showed a high degree of tolerance towards various sensitive functional groups such as hydroxyl, acetal, aldehyde, amine, imine, oxime, cyano and alkene. the Partner Organisations 2014.
