The CAS Registry Mumber 143394-49-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,3,9 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 143394-49:
(8*1)+(7*4)+(6*3)+(5*3)+(4*9)+(3*4)+(2*4)+(1*9)=134
134 % 10 = 4

Highly Functionalized Vinylcyclopropane Derivatives by Regioselective and Stereoselective Reactions of Fischer Carbene Complexes with 1,4-Disubstituted Electron-Deficient 1,3-Dienes

Buchert, Matthias,Reissig, Hans-Ulrich

, p. 2723 - 2730 (2007/10/02)

The thermal reaction of Fischer carbene complex 1 with electron-deficient 1,3-dienes such as methyl (E,E)-2,4-hexadienoate (2) provided functionalized vinylcyclopropanes like 3 in good yields.Similar results were obtained by employing related unsaturated
