The CA76128M1086 number you reference is a CUSIP code which identifies Resverlogix's industry.  It will show up on all manner of sites, any that have info on Resverlogix that includes the CUSIP...like the page in Stuttgart you found.  

Do a google search:  https://www.google.ca/search?q=CA76128M1086&rlz=1C1GCEB_enCA801CA801&oq=CA76128M1086&aqs=chrome..69i57&sourceid=chrome&{google:instantExtendedEnabledParameter}ie=UTF-8
