Template for formatting ISBN-10 numbers. Hypens and spaces are stripped out at the start.


The format for ISBN-10 is

<pre>[region]-[publisher]-[title]-[checkdigit]</pre>

the region is a fixed length (depending on where it came from), but the publisher and title fields can be any length, so they're currently grouped together.

==Examples==
<pre>{{FormatISBN10|4073055501|link=yes}}</pre>
{{FormatISBN10|4073055501|link=yes}}


<pre>{{FormatISBN10|5073 055501}}</pre>
{{FormatISBN10|5073 055501}}
