How to check whether a journal is still listed in Scopus?
The entry for this journal in Scopus lists "from 2009 to 2015" - it records 307 papers from 2015. The last issue they have indexed is vol. 10 issue 12, and they have not as yet indexed any 2016 papers.

The "to 2015" description seems to be standard for currently indexed journals; for example, Nature is listed as "1869 to 2015" despite being very much still alive. It doesn't automatically mean the journal has stopped being indexed - but the fact that Scopus does not list any 2016 papers yet does seem to suggest that it has stopped being indexed.

Note that Maxwell appears on Beall's list of potentially predatory publishers; while there are many caveats about Beall's work, it's certainly something to take note of.
