Calculate Digit Verification of CAS Registry Number 39500-17:
(7*3)+(6*9)+(5*5)+(4*0)+(3*0)+(2*1)+(1*7)=109
109 % 10 = 9
So 39500-17-9 is a valid CAS Registry Number.

, p. 3185 - 3187 (2002)

6-exo/endo-Trig intramolecular additions of aryl radicals to electron-rich, unsubstituted and electron-deficient arenes have all been shown to proceed efficiently to give the corresponding phenanthrenes in high yield.
