You can leave out the numbers at the end, that is just call

  update-rc.d my-program defaults

The sequence numbers are automatically calculated from the
dependencies by `insserv`. (Under both sysvinit and systemd.)

For older releases the specified number was relevant, but even the
documentation for `update-rc.d` in Wheezy documents the dependency-based
system; for Jessie and later the manual sequence numbers is even no
longer mentioned in the documentation (and always ignored anyway as far
as I know).
