132398-40-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 132398-40-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,3,9 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 132398-40:
(8*1)+(7*3)+(6*2)+(5*3)+(4*9)+(3*8)+(2*4)+(1*0)=124
124 % 10 = 4
So 132398-40-4 is a valid CAS Registry Number.

O-Nitrophenyl sulfoxides: Efficient precursors for the mild preparation of alkenes

Lu, Xiao,Long, Timothy E.

supporting information; experimental part, p. 249 - 252 (2010/04/06)

(Chemical Equation Presented) o-Nitrophenyl sulfoxides were found to be efficient synthetic precursors of various alkene types. The elimination occurs in toluene and NaOAc to generate substituted and terminal alkenes. Alkene products were easily obtained in high purity due to the simultaneous precipitation of the o-nitrophenyl sulfenic acid byproduct. The methods described have practical applications for the preparation of unsaturated compounds under mild, thermolytic conditions. 2009 American Chemical Society.

Generation and intramolecular cyclization of α-sulfinyl and α-sulfonyl radicals

Ke, Bor-Wen,Lin, Chao-Hsiung,Tsai, Yeun-Min

, p. 7805 - 7826 (2007/10/03)

α-Phenylsulfinyl and α-Phenylsulfonyl radicals are generated by the reactions of α-chlorosulfoxides and α-chlorosulfones with tributyltin hydride, respectively. High reaction concentration (0.2 M) is required to ensure efficient generations of these radic
