Calculate Digit Verification of CAS Registry Number 1279722-91:
(9*1)+(8*2)+(7*7)+(6*9)+(5*7)+(4*2)+(3*2)+(2*9)+(1*1)=196
196 % 10 = 6
So 1279722-91-6 is a valid CAS Registry Number.

Rhodium-catalyzed synthesis of 2,3-disubstituted indoles from β,β-Disubstituted stryryl azides

Sun, Ke,Liu, Sheng,Bec, Patryk M.,Driver, Tom G.

, p. 1702 - 1706 (2011/04/24)

Rings la carte: Rhodium carboxylate complexes catalyze selective cascade reactions to produce a range 2,3-disubstituted indoles from β,β- disubstituted stryryl azides. The selective migration of aryl groups appears to originate from a putative phenonium ion reactive intermediate (see scheme).
