Check Digit Verification of cas no

The CAS Registry Mumber 51786-43-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,7,8 and 6 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 51786-43:
(7*5)+(6*1)+(5*7)+(4*8)+(3*6)+(2*4)+(1*3)=137
137 % 10 = 7
So 51786-43-7 is a valid CAS Registry Number.

Rh(III)-catalyzed C-H alkylation of arenes using alkylboron reagents

Wang, He,Yu, Songjie,Qi, Zisong,Li, Xingwei

, p. 2812 - 2815 (2015)

Rhodium(III)-catalyzed direct alkylation of arenes using commercially available alkyltrifluoroborates is disclosed. Oximes, heteroarenes, azomethines, N-nitrosoamines, and amides are viable directing groups to entail this transformation. The alkyl group in the boron reagent can be extended to primary alkyls, benzyl, and cycloalkyls, and the reaction proceeded with controllable mono- and dialkylation selectivity when both ortho C-H sites are accessible.
