Calculate Digit Verification of CAS Registry Number 479213-74:
(8*4)+(7*7)+(6*9)+(5*2)+(4*1)+(3*3)+(2*7)+(1*4)=176
176 % 10 = 6
So 479213-74-6 is a valid CAS Registry Number.

Intramolecular triple heck reaction. An efficient entry to fused tetracycles with a benzene core

Ma, Shengming,Ni, Bukuo

, p. 8280 - 8283 (2007/10/03)

Twelve examples of 1,3,5-tribromo-2,4,6-trienylbenzenes were easily synthesized by alkylation, etherification, and amination methods. Under conditions A and B, a series of tetracycles with a benzene core, i.e., fused 5,6,6-, 6,6,6-, and 6,6,7-tetracyclic compounds, were prepared efficiently via this intramolecular triple Heck reaction protocol.
