109057-51-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 109057-51-4 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, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 109057-51:
(8*1)+(7*0)+(6*9)+(5*0)+(4*5)+(3*7)+(2*5)+(1*1)=114
114 % 10 = 4
So 109057-51-4 is a valid CAS Registry Number.

The Synthesis of Se-Alkyl Alkaneselenoates via (1-Iodo-1-alkenyl)dialkylboranes

Hoshi, Masayuki,Masuda, Yuzuru,Arase, Akira

, p. 3764 - 3766 (1988)

Se-Alkyl alkaneselenoates were formed in moderate to good yields by successive reactions of (1-iodo-1-alkenyl)bis(1,2-dimethylpropyl)boranes with alkylselenomagnesium bromides and alkaline hydrogen peroxide.

1-(organoselanyl)perfluoroalkanols: A stable and efficient precursor for organoselenols

Yamamoto, Terahisa,Moriura, Eri,Sawa, Arisa,Yoshimatsu, Mitsuhiro

experimental part, p. 1046 - 1047 (2009/12/03)

The 1-(organoselanyl)perfluoroalkanols 1, 3, 4, and 10 were successfully prepared and reactions with hexanoyl chlorides to produce the corresponding esters 5, 7, and 8, accompanied by the selenoesters 6 were conducted. The DBU-mediated alkylations of the heptafluorobutanols 4, 10, and the α-p-nitro-benzoate 2 with alkyl halides easily provided alkyl phenyl selenides 9a-9i and 11a-11c in good to high yields.

Synthesis of substituted Se-phenyl selenocarboxylates from terminal alkynes

Tiecco, Marcello,Testaferri, Lorenzo,Temperini, Andrea,Bagnoli, Luana,Marini, Francesca,Santi, Claudio,Terlizzi, Raffaella

, p. 3447 - 3458 (2007/10/03)

Se-Phenyl selenocarboxylates have been conveniently prepared from (phenylseleno)acetylenes by treatment with p-toluenesulfonic acid monohydrate in dichloromethane. This easy conversion is compatible with a broad range of oxygen- and nitrogen-containing functional groups. The Se-phenyl selenocarboxylates were easily converted into the corresponding esters and amides. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004.

Cleavage of Se-Se bond by Sm/cat. Cocl2 system: A novel method for the synthesis of selenoesters

Chen, Rener,Zhang, Yongmin

, p. 1331 - 1336 (2007/10/03)

The Sm/cat. COCl2 system promoted desalinates to react with anhydrides or acyl chlorides to afford selenoesters in good yield under mild and neutral conditions.
