Check Digit Verification of cas no

The CAS Registry Mumber 1220909-56-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,0,9,0 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1220909-56:
(9*1)+(8*2)+(7*2)+(6*0)+(5*9)+(4*0)+(3*9)+(2*5)+(1*6)=127
127 % 10 = 7
So 1220909-56-7 is a valid CAS Registry Number.

Synthesis and in vitro evaluation of imidazo[1,2- b ]pyridazines as ligands for β-amyloid plaques

Zeng, Fanxing,Alagille, David,Tamagnan, Gilles D.,Ciliax, Brian J.,Levey, Allan I.,Goodman, Mark M.

scheme or table, p. 80 - 84 (2010/11/05)

A series of imidazo[1,2-b]pyridazine derivatives were synthesized and evaluated for binding to amyloid plaques in vitro using synthetic aggregates of Aβ1?40. Binding affinities of these compounds were found to range from 11.0 to >1000 nM, depending on the various substitution patterns in the 6-position and 2-position. 2-(4′-Dimethylaminophenyl)-6- (methylthio)imidazo[1,2-b]pyridazine (4) showed high binding affinity (K i = 11.0 nM) and might be useful for the development of novel positron emission tomography radiotracers for imaging Aβ plaques.
