Check Digit Verification of cas no
The CAS Registry Mumber 343781-56-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,3,7,8 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 343781-56:
(8*3)+(7*4)+(6*3)+(5*7)+(4*8)+(3*1)+(2*5)+(1*6)=156
156 % 10 = 6
So 343781-56-6 is a valid CAS Registry Number.

Strategies for the selective functionalization of dichloropyridines at various sites
Marzi, Elena,Bigi, Anna,Schlosser, Manfred
, p. 1371 - 1376 (2007/10/03)
Whereas 2,3-dichloropyridine and 2,5-dichloro-4-(lithiooxy)-pyridine undergo deprotonation exclusively at the 4- and 2-positions, respectively, optional site selectivity can be implemented with 2,5- and 3,4-dichloropyridine (which are attacked, depending on the choice of the reagents, at either the 4- or 6- and either the 2- and 5-positions, respectively). Upon treatment with lithium diisopropylamide, 2,4-dichloro-3-iodopyridine, 3,5-dichloro-4-bromopyridine and 2,6-dichloro-3-iodopyridine afford 5-, 2- and 4-lithiated intermediates, but the latter isomerize instantaneously to species in which lithium and iodine have swapped places, the driving force being the low basicity of C-Li bonds when flanked by two neighboring halogens.
