Calculate Digit Verification of CAS Registry Number 431947-09:
(8*4)+(7*3)+(6*1)+(5*9)+(4*4)+(3*7)+(2*0)+(1*9)=150
150 % 10 = 0
So 431947-09-0 is a valid CAS Registry Number.

Synthesis of 7-azabicyclo[2.2.1]heptane derivatives via bridgehead radicals

Avenoza, Alberto,Busto, Jesús H,Cativiela, Carlos,Peregrina, Jesús M

, p. 1193 - 1197 (2002)

This report shows the versatility and synthetic potential of 7-azabicyclo[2.2.1]heptane-1-carboxylic acid (Ahc) to obtain several bridgehead 1-substituted-7-azabicyclo[2.2.1]heptane derivatives, including halogen derivatives, via bridgehead radical reactions, proving the existence of the bridgehead radical in 7-azabicyclo[2.2.1]heptane systems. Moreover, we have obtained the interesting compound N-benzoyl-7-azabicyclo[2.2.1]heptane, a precursor of epibatidine.
