Calculate Digit Verification of CAS Registry Number 154050-88:
(8*1)+(7*5)+(6*4)+(5*0)+(4*5)+(3*0)+(2*8)+(1*8)=111
111 % 10 = 1
So 154050-88-1 is a valid CAS Registry Number.

Synthesis Of Highly Substituted Pyridines Through Nucleophilic Substitution Of Tetrachloro-3-Cyanopyridine

Chapyshev, Sergei V.,Ibata, Toshikazu

, p. 2185 - 2190 (2007/10/02)

Tetrachloro-3-cyanopyridine reacts with anilines and/or sodium azide through replacement of three chlorine atoms at the 2-, 4-, and 6-positions, whereas with difunctional nucleophiles by replacement of chlorines at the 5- and 6-positions.Using these reactions synthesis of highly substituted pyridines has been developed.
