Calculate Digit Verification of CAS Registry Number 98203-15:
(7*9)+(6*8)+(5*2)+(4*0)+(3*3)+(2*1)+(1*5)=137
137 % 10 = 7
So 98203-15-7 is a valid CAS Registry Number.

Palladium-Catalyzed Coupling of 2-Bromoanilines with Vinylstannanes. A Regiocontrolled Synthesis of Substituted Indoles

Krolski, Michael E.,Renaldo, Alfred F.,Rudisill, Duane E.,Stille, J. K.

, p. 1170 - 1176 (2007/10/02)

The palladium-catalyzed cross-coupling reaction of aryl halides and triflates with vinylstannane reagents has been used to produce a variety of substituted indoles.The mild reaction conditions and selectivity inherent in the coupling reaction have been utilized to produce regiochemically pure 4-, 5-, and 6-substituted indoles.
