Check Digit Verification of cas no
The CAS Registry Mumber 837364-87-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,3,7,3,6 and 4 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 837364-87:
(8*8)+(7*3)+(6*7)+(5*3)+(4*6)+(3*4)+(2*8)+(1*7)=201
201 % 10 = 1
So 837364-87-1 is a valid CAS Registry Number.

Regiochemically flexible substitutions of di-, tri-, and tetrahalopyridines: The trialkylsilyl trick
Schlosser, Manfred,Bobbio, Carla,Rausis, Thierry
, p. 2494 - 2502 (2007/10/03)
(Chemical Equation Presented) 2,4-Difluoropyridine, 2,4-dichloropyridine, 2,4,6-trifluoropyridine, 2,4,6-trichloropyridine and 2,3,4,6-tetrafluoropyridine react with standard nucleophiles exclusively at the 4-position under halogen displacement. However, the regioselectivity can be completely reversed if a trialkylsilyl group is introduced in the 5-position of the 2,4-dihalopyridines or in the 3-position of the 2,4,6-trihalopyridines or 2,3,4,6-tetrahalopyridine. Then only the halogen most remote from the bulky silyl unit (at the 2-position in the case of the 2,4-halopyridines, at the 6-position with the other substrates) gets involved in the exchange process. After removal of the silyl protective group the nucleophile is invariably found to occupy the nitrogen-neighboring position.
