140927-12-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 140927-12-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,9,2 and 7 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 140927-12:
(8*1)+(7*4)+(6*0)+(5*9)+(4*2)+(3*7)+(2*1)+(1*2)=114
114 % 10 = 4
So 140927-12-4 is a valid CAS Registry Number.

Synthesis of epibatidine isomers: endo-5- and 6- (6′-chloro-3′-pyridyl-2-azabicyclo[2.2.1]heptanes
Cox,Malpass,Gordon,Rosen
, p. 2372 - 2379 (2007/10/03)
Synthesis of the title compounds is described; detailed NMR data are provided in support of the proposed stereostructures. The 5- and 6-endo-compounds show high selectivity for α4β2 versus α7 nAChR subtypes; in contrast, the exo-stereoisomers show compara
