How good is my regex

[Captain Paralytic]

I need to validate that a string meets the following criteria.

Is at least 1 digit > 0 (1-9)
May contain commas, hyphens and spaces
Must begin with a digit (1-9)
Must end with a digit (0-9)
Any new group of digits (either the first in the string or immediately
following a comma, space or hyphen) must begin with (1-9)

So:
good
1
123
1 456-567,676

bad
01
123,
,345
123 0456
123,345-087

I've come up with a couple of REGEXs but I'm no regexpert (geddit - I
know, no comedian either), but I'm sure there's a tidier way.

Looks neater than mine (no surprise there - and I discovered that mine
didn't do all of the rules either!). I'll try it out tonight. Thanks.
