DOI names contain two parts: prefix and suffix separated by a forward slash.
Prefix: directory indicator '10.' followed by a registrant code
Suffix: character string of any length chosen by the registrant
This function checks a DOI name for: prefix/suffix. If the doi name contains spaces or endashes, or, if it ends

DOI names are case-insensitive and can incorporate any printable Unicode characters so the test for spaces, endash,
