Yes, I agree with this.
I believe that Luhn algorithm function got check digit, so if this check digit could be placed in front this could be
achieved.

My unscientific suggestion is to combine a leading random number between 1
and 9 with the trailing 4 digit (With leading zeros) number so that you
never have the first digit of the SKU be a zero.
Too many technical issues with all numeric strings containing leading zeros;
and I think human ones too.
