Check Digit Verification of cas no
The CAS Registry Mumber 3084-53-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,8 and 4 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3084-53:
(6*3)+(5*0)+(4*8)+(3*4)+(2*5)+(1*3)=75
75 % 10 = 5
So 3084-53-5 is a valid CAS Registry Number.

Influence of Temperature on the Liquid-Liquid Equilibrium of the Ternary System Acetonitrile-2-Furyloxirane-Cyclohexane
Rakotondramanana, Samuel,Borredon, Marie-Elisabeth,Molinier, Jacques
, p. 306 - 308 (1987)
2-Furyloxirane can be obtained by a low hydrated solid-liquid phase transfer process from furfural and a sulfonium salt in basic medium by using acetonitrile as a solvent.It is purified by extraction in a reactive medium with an extracting solvent, cyclohexane.Diagrams on solubility isotherms and tie-line data are given for the ternary system acetonitrile-2-furyloxirane-cyclohexane at 20-30 and 40 deg C.Under these conditions 2-furyloxirane extraction by cyclohexane appears not to depend on temperature.

Thiophene-based rings are one of the most widely used building blocks for the synthesis of sulfur-containing molecules. Inspired by the redox diversity of these features in nature, we demonstrate herein a redox-divergent construction of dihydrothiophenes, thiophenes, and bromothiophenes from the respective readily available allylic alcohols, dimethyl sulfoxide (DMSO), and HBr. The redox-divergent selectivity could be manipulated mainly by controlling the dosage of DMSO and HBr. Mechanistic studies suggest that DMSO simultaneously acts as an oxidant and a sulfur donor. The synthetic potentials of the products as platform molecules were also demonstrated by various derivatizations, including the preparation of bioactive and functional molecules.
