Calculate Digit Verification of CAS Registry Number 1223418-49:
(9*1)+(8*2)+(7*2)+(6*3)+(5*4)+(4*1)+(3*8)+(2*4)+(1*9)=122
122 % 10 = 2
So 1223418-49-2 is a valid CAS Registry Number.

p-TsOH promoted Fischer indole synthesis of multi-substituted 2-trifluoromethyl indole derivatives

Jiang, Haizhen,Wang, Yangli,Wan, Wen,Hao, Jian

experimental part, p. 2746 - 2751 (2010/05/02)

A p-TsOH promoted one-pot synthesis of multi-substituted 2-trifluoromethyl indole derivatives, for instance, 2-trifluoromethyl-3-phenylindoles, 2-trifluoromethyl-indole-3-propanoates, and 2-trifluoromethyl-indole-3-butanoates from reactions of 1,1,1-trifluoro-3-phenylacetone and simply prepared ω-trifluoromethyl substituted δ and ε-ketoesters with arylhydrazines via Fischer indole synthesis has been developed.
