Many publishers include the DOI along with other citation information on the first page of an article. If you have a PDF of the article examine it to look for the DOI in the margins, header, and footer.
CrossRef.org is the organization that facilitates the creation and use of DOIs by publishers and scholars. Its database contains citation information for all articles that have been assigned DOIs. You can search it using the article information you have to find out what the DOI is.
