Calculate Digit Verification of CAS Registry Number 87304-84:
(7*8)+(6*7)+(5*3)+(4*0)+(3*4)+(2*8)+(1*4)=145
145 % 10 = 5

Stereochemistry of the Bicyclopentane Ringopening; Thermolysis of Tricyclo2,4>heptane Derivatives

Roth, Wolfgang R.,Klaerner, Frank-Gerit,Grimme, Wolfram,Koeser, Hans G.,Busch, Ralf,et al.

, p. 2717 - 2737 (2007/10/02)

Thermolysis of the anti-tricyclic compounds 6, 22 and 34 proceeds preferentially by concerted 2s+?2a>-reactions and leads to cis,trans-olefines 8, 24 and 37.The rearrangement of the syn-isomers on the other hand seems to be a nonconcerted reaction yielding the diradicals 15, 27 and 36.
