Check Digit Verification of cas no

The CAS Registry Mumber 1612774-95-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,2,7,7 and 4 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1612774-95:
(9*1)+(8*6)+(7*1)+(6*2)+(5*7)+(4*7)+(3*4)+(2*9)+(1*5)=174
174 % 10 = 4
So 1612774-95-4 is a valid CAS Registry Number.

Ruthenium-catalyzed cross-dehydrogenative ortho-N-carbazolation of diarylamines: Versatile access to unsymmetrical diamines

Louillat, Marie-Laure,Biafora, Agostino,Legros, Fabien,Patureau, Frederic W.

, p. 3505 - 3509 (2014/04/03)

The dehydrogenative C-N cross-coupling of unprotected, secondary anilines through ortho-N-carbazolation has been achieved using a Ru catalytic system with O2 as the terminal oxidant. The reactions proceed in an intermolecular fashion, selectively in the ortho position. Implications for the field of organic synthesis are discussed. No-No-No: Amination of a non-acidic Ci£H bond, no pre-activation of the coupling partners, no chelate-assisting directing group. Dehydrogenative C-N cross-coupling through the ortho-N-carbazolation of unprotected, secondary anilines has been achieved using a Ru catalyst with O2 as the terminal oxidant.
