How do I check if an ISSN is properly registered with issn.org? I found a tip on wikipedia to try link like "http://www.worldcat.org/ISSN/1021-9749" to see if an ISSN is registered, but for the ISSN in question (2032-9393) the link does not return an entry. Does it mean that the ISSN is not registered?
Based on their guidelines for requesting an ISSN, I would try their contact email and ask for confirmation: email@example.com . Let us know if that works :)
