49 % 10 = 9
So 20122-48-9 is a valid CAS Registry Number.

Synthesis and radioligand binding studies of methoxylated 1,2,3,4-tetrahydroisoquinolinium derivatives as ligands of the apamin-sensitive Ca2+-activated K+ channels

Graulich, Amaury,Scuvée-Moreau, Jacqueline,Alleva, Livia,Lamy, Cédric,Waroux, Olivier,Seutin, Vincent,Liégeois, Jean-Fran?ois

, p. 7208 - 7214 (2007/10/03)

Several methoxylated 1,2,3,4-tetrahydroisoquinoliniums derived from N-methyl-laudanosine and N-methyl-noscapine were synthesized and evaluated for their affinity for apamin-sensitive binding sites. The quaternary ammonium derivatives have a higher affinit
