Check Digit Verification of cas no

The CAS Registry Mumber 201486-97-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,4,8 and 6 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 201486-97:
(8*2)+(7*0)+(6*1)+(5*4)+(4*8)+(3*6)+(2*9)+(1*7)=117
117 % 10 = 7
So 201486-97-7 is a valid CAS Registry Number.

Site-Selective C(sp3)–H Functionalization of Fluorinated Alkanes Driven by Polar Effects Using a Tungstate Photocatalyst

Fukuyama, Takahide,Nishikawa, Tomohiro,Ryu, Ilhyong

, p. 1424 - 1428 (2020)

The TBADT-catalyzed C(sp3)–H functionalization of perfluorophenyl- and perfluoroalkyl-substituted alkanes was studied to determine how the fluorous substituents affect site-selectivity. Alkylation of alkyl-substituted perfluorobenzene avoids α-C–H bonds, unlike their alkylbenzene counterparts, allowing site-selective functionalization of C–H bonds remote to the aromatic ring. Alkylation of alkanes having a perfluoroalkyl group also avoided α-C–H bonds. Radical polar effects in the SH2 transition states could explain this avoidance of α-C–H functionalization.
