Presuming you mean:
then that should be ok. What do you mean by 'it doesn't work'?
Using cron for this is a bit gross though as it will contribute towards the system beating.
A while loop with a sleep achieves the same thing without the beating.

set::crontab
Crontab(3) User Contributed Perl Documentation Crontab(3)NAME
Set::Crontab - Expand crontab(5)-style integer lists
SYNOPSIS
$s = Set::Crontab->new("1-9/3,>15,>30,!23", [0..30]);
if ($s->contains(3)) { ... }
DESCRIPTION
Set::Crontab parses crontab-style lists of integers and defines some utility functions to make it easier to deal with them.
Syntax
Numbers, ranges, *, and step values all work exactly as described in crontab(5). A few extensions to the standard syntax are described
below.
< and >
<N selects the elements smaller than N from the entire range, and adds them to the set. >N does likewise for elements larger than N.
! !N excludes N from the set. It applies to the other specified range; otherwise it applies to the specified ranges (i.e. "!3" with a
range of "1-10" corresponds to "1-2,4-10", but ">3,!7" in the same range means "4-6,8-10").
Functions
new($spec, [@range])
Creates a new Set::Crontab object and returns a reference to it.
contains($num)
Returns true if $num exists in the set.
list()
Returns the expanded list corresponding to the set.
The functions described above croak if they are called with incorrect arguments.
