Very odd that Hydrogen Cyanide (Prussic acid) is classified as organic, while Sodium Cyanide is inorganic… Must be logic invented by a man! 
Hydrogen Cyanide HCN has Carbon and Hydrogen hence organic.
Sodium Cyanide NaCN has carbon but no Hydrogen hence inorganic.
You doing a little research on Cyanide are we? Someone bothering you? 
I loved inorganic chemistry when I was at school. Organic chemistry though, ugh, that was a whole different can of worms!
