Check Digit Verification of cas no
The CAS Registry Mumber 851179-01-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,1,1,7 and 9 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 851179-01:
(8*8)+(7*5)+(6*1)+(5*1)+(4*7)+(3*9)+(2*0)+(1*1)=166
166 % 10 = 6
So 851179-01-6 is a valid CAS Registry Number.

Removal of fluorine from and introduction of fluorine into polyhalopyridines: An exercise in nucleophilic hetarenic substitution
Bobbio, Carla,Rausis, Thierry,Schlosser, Manfred
, p. 1903 - 1910 (2007/10/03)
Starting from six industrially available fluorinated pyridines, an expedient access to all three tetrafluoropyridines (2-4), all six trifluoropyridines (5-10), and the five non-commercial difluoropyridines (11-14 and 16) was developed. The methods employed for the selective removal of fluorine from polyfluoropyridines were the reduction by metals or complex hydrides and the site-selective replacement by hydrazine followed by dehydrogenation-dediazotation or dehydrochlorination-dediazotation. To introduce an extra fluorine atom, a suitable precursor was metalated and chlorinated before being subjected to a chlorine/ fluorine displacement process.
