Check Digit Verification of cas no

The CAS Registry Mumber 42473-85-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,4,7 and 3 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 42473-85:
(7*4)+(6*2)+(5*4)+(4*7)+(3*3)+(2*8)+(1*5)=118
118 % 10 = 8
So 42473-85-8 is a valid CAS Registry Number.

Regioselective gold-catalyzed oxidative C-N bond formation

Marchetti, Louis,Kantak, Abhishek,Davis, Riley,Deboef, Brenton

, p. 358 - 361 (2015)

A novel protocol for the regioselective intermolecular amination of various arenes has been developed. By using an I(III) oxidant in the presence of a Au(I) catalyst, a direct and novel route for regioselectively accessing a variety of substituted aniline moieties has been achieved with yields as high as 90%. Mechanistic insight suggests that regioselectivity can be predicted based on electrophilic aromatic metalation patterns.
