Check Digit Verification of cas no

The CAS Registry Mumber 1428346-04-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,3,4 and 6 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1428346-04:
(9*1)+(8*4)+(7*2)+(6*8)+(5*3)+(4*4)+(3*6)+(2*0)+(1*4)=156
156 % 10 = 6
So 1428346-04-6 is a valid CAS Registry Number.

Palladium-catalyzed oxidative C-N bond coupling involving a solvent-controlled regioselective bromination process

Ji, Xiaochen,Huang, Huawen,Xiong, Wenfang,Huang, Kunbo,Wu, Wanqing,Jiang, Huanfeng

, p. 7005 - 7011 (2014/08/18)

Stereoselective palladium-catalyzed oxidative C-N bond coupling reactions between aromatic amines and alkenes involving a solvent-controlled regioselective bromination process under 1 atm of oxygen atmosphere are disclosed, providing easy access to two different brominated enamines. The addition of hydrogen peroxide (30% aq) as a co-oxidant in the system is crucial for the dehydrogenative aminohalogenation under molecular oxygen (1 atm), and in such a case, the C-N bond coupling/electrophilic bromination reaction cascade is proposed. Furthermore, the different reaction media leads to a switched regioselectivity of the process.
