Use UnityWebRequest.Head and check responseCode, if >= 400 then file does not exits (according to wikipedia)

If you are using UnityEngine.WWW to make the web request then you can check the error member from UnityEngine.WWW

its also possible to get the verbose text of the response and parse it for the http status code.
