1452261-70-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1452261-70-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,2,2,6 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1452261-70:
(9*1)+(8*4)+(7*5)+(6*2)+(5*2)+(4*6)+(3*1)+(2*7)+(1*0)=139
139 % 10 = 9
So 1452261-70-9 is a valid CAS Registry Number.

A one-pot stereoselective synthesis of electron-deficient 4-substituted (E, E)-1-arylsulfonylbuta-1,3-dienes and their chemoselective [3+2] cycloaddition with azomethine ylides - A simple synthesis of 1,3,4-trisubstituted pyrrolidines and pyrroles

Sankar, Ulaganathan,Mahalakshmi, Susarla,Balasubramanian, Kalapattukuppuswamy

, p. 1533 - 1540 (2013)

A simple and efficient method for the synthesis of (E,E)-1-(arylsulfonyl) buta-1,3-dienes bearing electron-withdrawing substituents like cyano and ethoxycarbonyl at position 4, involving a one-pot alkylation of bis(phenylsulfonyl)methane with trans-ethyl 4-bromocrotonate/trans-4- bromocrotononitrile, and elimination of arylsulfinic acid, is described. These dienes undergo facile mono [3+2] cycloaddition with azomethine ylides chemoselectivity to furnish functionalized 1,3,4-trisubstituted pyrrolidines. Oxidation of these cycloadduct with MnO2·SiO2 under mild conditions provides 1,3,4-trisubstituted pyrroles. Georg Thieme Verlag Stuttgart. New York.
