Check Digit Verification of cas no

The CAS Registry Mumber 42817-57-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,8,1 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 42817-57:
(7*4)+(6*2)+(5*8)+(4*1)+(3*7)+(2*5)+(1*7)=122
122 % 10 = 2
So 42817-57-2 is a valid CAS Registry Number.

Harnessing Alkyl Amines as Electrophiles for Nickel-Catalyzed Cross Couplings via C-N Bond Activation

Basch, Corey H.,Liao, Jennie,Xu, Jianyu,Piane, Jacob J.,Watson, Mary P.

supporting information, p. 5313 - 5316 (2017/04/27)

We developed a strategy to harness alkyl amines as alkylating agents via C-N bond activation. This Suzuki-Miyaura cross coupling of alkylpyridinium salts, readily formed from primary amines, is the first example of a metal-catalyzed cross coupling via C-N bond activation of an amine with an unactivated alkyl group. This reaction enjoys broad scope and functional group tolerance. Primary and secondary alkyl groups can be installed. Preliminary studies suggest a NiI/NiIII catalytic cycle.
