Calculate Digit Verification of CAS Registry Number 925900-89:
(8*9)+(7*2)+(6*5)+(5*9)+(4*0)+(3*0)+(2*8)+(1*9)=186
186 % 10 = 6
So 925900-89-6 is a valid CAS Registry Number.

An efficient synthesis of fused tricycles with a benzene core via intramolecular double ring-closing enyne metathesis

Liang, Zhiqiang,Ma, Shengming,Yu, Jihong,Xu, Ruren

, p. 977 - 985 (2007/10/03)

A double enyne metathesis reaction has been developed for the efficient synthesis of tricyclic products with a benzene core in good yields. By this protocol, bisannulated benzenes with different ring sizes may be simultaneously constructed from the corres
