40340-02-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 40340-02-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,3,4 and 0 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 40340-02:
(7*4)+(6*0)+(5*3)+(4*4)+(3*0)+(2*0)+(1*2)=61
61 % 10 = 1
So 40340-02-1 is a valid CAS Registry Number.

On the reactivity of indium(III) benzenechalcogenolates (chalcogen = sulfur and selenium) towards organyl halides for the synthesis of organyl phenyl chalcogenides

Peppe, Clovis,Borges De Castro, Lierson

experimental part, p. 678 - 683 (2009/10/30)

The reactivity of indium(III) benzenechalcogenolates (chalcogen = sulfur, selenium) towards organyl halides (organyl = alkyl, allyl, benzyl, acyl) was examined. A practical one-pot method to prepare organyl phenyl chalcogenides indium metal and diphenyl dichalcogenide was found. The coupling is fairly broad in scope and generally works better organyl halides capable to produce stable carbocations.

Ionic liquid as catalyst and reaction medium: A simple, convenient and green procedure for the synthesis of thioethers, thioesters and dithianes using an inexpensive ionic liquid, [pmIm]Br

Ranu, Brindaban C.,Jana, Ranjan

, p. 1811 - 1818 (2007/10/03)

An easily accessible and inexpensive room temperature ionic liquid, 1-pentyl-3-methylimidazolium bromide, [pmIm]Br efficiently catalyzes the reaction of alkyl halides or acyl halides with thiols without any solvent at room temperature leading to the synthesis of thioethers and thioesters in high yields. This reaction has also been extended for the preparation of dithianes and transthioetherification. The ionic liquid is recovered and recycled for subsequent runs.

Unusual cleavage of ethers by thiophenol on the surface of silica gel impregnated with indium(III) chloride under microwave irradiation: Efficient procedure for the synthesis of thioethers through transthioetherification

Ranu, Brindaban C.,Samanta, Sampak,Hajra, Alakananda

, p. 987 - 989 (2007/10/03)

Cyclic and open-chain benzylic ethers undergo cleavage by thiophenol on the surface of silica gel impregnated with indium(III) chloride under microwave irradiation to produce the corresponding di- and monothioethers.
