A basic expression which would allow commas to occur anywhere in the number string:
m/^[0-9,]+$/
Or an untested expression which would allow a comma after the first number or not, then after every 3 numbers or not, although it would allow i.e. "1,234,56789,444":
m/^\d\,?(\d{1,2}|\d{3}\,?)*$/
Sometimes I wonder if it would be easier to validate that the string contains just numbers or commas, remove all commas, then use sprintf to replace the commas in their proper places.
