Tool for mapping references to endnote style? - (Oct/28/2013 )

Is there a tool which allows you to identify the style of references and citations in an article.  I have a book chapter but don't know in which journal style the references are formatted. 

When you go to endnote in word > search references > the external endnote program opens > do you see a drop down menu with formatting styles? I have version X5. You can also find this info in edit > output styles.

Good?
