Calculate Digit Verification of CAS Registry Number 108293-72:
(8*1)+(7*0)+(6*8)+(5*2)+(4*9)+(3*3)+(2*7)+(1*2)=127
127 % 10 = 7
So 108293-72-7 is a valid CAS Registry Number.

Intramolecular ketone-olefin radical cyclization with low-valent titanium reagent: Synthesis of benzopyrans

Nayak, Sandip K.,Bhatt, Suchitra,Roy, Kshama

scheme or table, p. 2969 - 2975 (2010/11/05)

A novel protocol for intramolecular ketyl-olefin radical cyclization with low-valent titanium reagent is outlined. It allows the formation of the benzopyran nucleus from ortho-allyloxy propiophenones as the sole product in moderate yields via intramolecular radical cyclization.
