109057-62-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 109057-62-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,0,5 and 7 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 109057-62:
(8*1)+(7*0)+(6*9)+(5*0)+(4*5)+(3*7)+(2*6)+(1*2)=117
117 % 10 = 7
So 109057-62-7 is a valid CAS Registry Number.

Acylation of diselenides and disulfides with N-acylbenzotriazoles promoted by SmI2

Tu, Ya Wei,Zhou, Lie Jin,Lv, Xin,Wang, Xiao Xia

, p. 435 - 439 (2014/05/06)

The acylation of diselenides or disulfides with N-acylbenzotriazoles mediated by SmI2 has been achieved successfully without the presence of HMPA, and the corresponding selenolesters or thioesters have been prepared in good yields.

Indium-mediated cleavage of diphenyl diselenide and diphenyl disulfide: efficient one-pot synthesis of unsymmetrical diorganyl selenides, sulfides, and selenoesters

Munbunjong, Wanida,Lee, Eun Hwa,Ngernmaneerat, Poonlarp,Kim, Sung Jun,Singh, Gurpinder,Chavasiri, Warinthorn,Jang, Doo Ok

experimental part, p. 2467 - 2471 (2009/08/15)

A convenient and efficient method was developed for the synthesis of alkyl phenyl selenides, sulfides, and selenoesters in one-pot reaction by using indium metal. The reaction showed the selectivity for tert-alkyl, benzylic, and allylic halides over primary and secondary alkyl halides. For the reaction of primary and secondary alkyl iodides and bromides, the yields of selenides were improved by the addition of a catalytic amount of iodine.

Reductive cleavage of the Se-Se bond in the presence of a Zn/AlCl 3 system: Synthesis of selenol esters

Movassagh, Barahman,Shamsipoor, Mojgan,Joshaghani, Mohammad

, p. 148 - 149 (2007/10/03)

Selenol esters were prepared in good yields by reacting diselenides with carboxylic acid anhydrides in dry acetonitrile in the presence of a Zn/AlCl 3 system.
