A free DOI lookup tool is available from CrossRef, linked below.

Alternately, if you need the DOI of a journal article that's indexed in PubMed, try using PubMed to find the needed number:

  1. Find the PubMed record for the article (PubMed's single citation matcher may be helpful).
  2. The DOI is visible in the summary and abstract views
