13920-89-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 13920-89-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,9,2 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 13920-89:
(7*1)+(6*3)+(5*9)+(4*2)+(3*0)+(2*8)+(1*9)=103
103 % 10 = 3
So 13920-89-3 is a valid CAS Registry Number.

Solvent-free anti-markovnikov addition of thiols to alkenes using anhydrous cerium(III) chloride as catalyst

Silveira, Claudio C.,Mendes, Samuel R.,Líbero, Francieli M.

experimental part, p. 790 - 792 (2010/06/13)

The anti-Markovnikov addition of thiols to alkenes using CeCl3 as catalyst is described. The products were obtained in good to excellent yields. The reaction occurred under solvent-free conditions at room temperature.

N-Phenyltriazolinedione as an initiator in the radical addition of thiophenol to alkenes

Nicolaou, Georgia,Elemes, Yiannis

body text, p. 6324 - 6326 (2009/04/06)

N-Phenyltriazolinedione is found to be an efficient initiator in the radical (anti-Markovnikov) addition of thiophenol to 2-methyl-2-butene. A second, minor, product (an alcohol, from oxygen addition) was also obtained, and a possible mechanistic scheme is proposed.

ELECTROREDUCTIVE CLEAVAGE OF CARBON-SULPHUR BONDS IN DITHIOACETALS

Itter, Nicola Schultz-von,Steckhan, Eberhard

, p. 2475 - 2484 (2007/10/02)

The carbon-sulphur bond in aliphatic diphenyldithioacetals, α-carbonyldiphenyldithioacetals and α-carbonylketene dimethyldithioacetals can be cleaved cathodically on mercury (Hg) or glassy carbon (GC) electrodes.In the presence of tetrabutylammoniumhydrog

TITANIUM TETRACHLORIDE PROMOTED REDUCTION OF ALKENYL SULFIDES USING TRIETHYLSILANE AS A REDCING AGENT

Takeda, Takeshi,Tsuchida, Toshio,Fujiwara, Tooru

, p. 1219 - 1220 (2007/10/02)

Alkenyl sulfides were reduced to the corresponding alkyl sulfides with triethylsilane in the presence of titanium tetrachloride in good yields.The reduction proceeds via -phenylthio-alkyltitanium intermediate.
