The CAS Registry Mumber 1258459-75-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,4,5 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1258459-75:
(9*1)+(8*2)+(7*5)+(6*8)+(5*4)+(4*5)+(3*9)+(2*7)+(1*5)=194
194 % 10 = 4

Regio- and stereo-selective synthesis of tetrasubstituted olefins by the three-component tandem reaction of phenylselenomagnesium bromide, acetylenic sulfones and allylic bromides

Huanga, Bin,You, Shengyong,Cai, Mingzhong

, p. 127 - 129 (2010)

Tetrasubstituted olefins containing a 1,4-diene structural unit can be regio- and stereo-selectively synthesised in good yields under mild conditions, in one pot, by Michael addition of phenylselenomagnesium bromide to acetylenic sulfones, followed by coupling with allylic bromides.
