How to retrieve DOI from file name automatically?


I just downloaded a ton of PDFs that do not have DOIs in the copytext, but the file name is the DOI. This seems to be a standard for Wiley, since all of them are from Wiley databases.

Now, I can copy these DOIs to the field individually and then manually choose Find Reference Updates… but that takes long and many clicks and fiddling, compared to EndNote downloading the data automatically upon import. 

Does anyone know how the DOI can be retrieved automatically from the filename?
