Calculate Digit Verification of CAS Registry Number 757191-46:
(8*7)+(7*5)+(6*7)+(5*1)+(4*9)+(3*1)+(2*4)+(1*6)=191
191 % 10 = 1
So 757191-46-1 is a valid CAS Registry Number.

Oxidation-resistant, sterically demanding phenanthrolines as supporting ligands for copper(I) nitrene transfer catalysts

Hamilton, Charles W.,Laitar, David S.,Sadighi, Joseph P.

, p. 1628 - 1629 (2004)

New 1,10-phenanthroline ligands have been synthesized with C 6F5- or 2,4,6-(CF3)3C 6H2- groups in the 2- and 9-positions; a cationic copper(I) complex of the latter catalyses nitrene transfer to the C-H bonds of electron-rich arenes.
