Try this:

^(?:\d+[,-]?)+\d+$

it matches bare numbers like 23 too.
You can test it in this site.

Try this:

^(?:[0-9]+[,-])+[0-9]+$

Explanation:

^         # Start of string
(?:       # Try to match:
 [0-9]+   #  one or more digits
 [,-]     #  one separator (- or ,)
)+        # once or more.
[0-9]+    # Match one or more digits
$         # End of string
