Check Digit Verification of cas no
The CAS Registry Mumber 209328-85-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,9,3,2 and 8 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 209328-85:
(8*2)+(7*0)+(6*9)+(5*3)+(4*2)+(3*8)+(2*8)+(1*5)=138
138 % 10 = 8
So 209328-85-8 is a valid CAS Registry Number.

The structural proliferation of 2,6-difluoropyridine through organometallic intermediates
Schlosser, Manfred,Rausis, Thierry
, p. 1018 - 1024 (2007/10/03)
Contrary to a literature claim, 2,6-difluoropyridine-3-carboxaldehyde can be readily prepared by consecutive treatment of 2,6-difluoropyridine with lithium diisopropylamide and N,N-dimethylformamide. Regioselective displacements of fluorine from the aldehyde by nucleophiles were carried out. To demonstrate the versatility of the organometallic approach, some two dozens of further 2,6-difluoropyridine derivatives were prepared applying a combination of modern organometallic methods such as site selective hydrogen/metal and halogen/metal permutations and deprotonation-triggered heavy halogen migrations.
