Is it possible to get DOI from ISBN of a book? I need DOI number of the book with ISBN 9780723437512. There is a kindle edition so it should have some electronic identification. 



How can you get DOI from ISBN?
DOI and ISBN are two different identification numbers and can not be translated into each other. A (digital) book need not have a DOI number, and e.g. a journal article that has a DOI need not have an ISBN number.

If you want to look up whether a book (or journal article, etc.) has a DOI, you can query it at http://www.crossref.org/guestquery
