is_single array not working

I am trying to conditionally hide ads on certain posts. I’ve used both post ID’s and post slugs/titles and am no further ahead.

The problem is that the following codes, added into the template file (single.php) only seem to either only acknowledge a single post ID or the first ID in a string. The array (which I am betting is syntactically correct) doesn’t work at all.

this works – hides code on post ID #30:

<code><?php if( !is_single('30') ) : ?>
~ ad code goes here ~
<?php endif; ?></code>

this partially works – hides code only post ID #30 but not on others:

<?php if( !is_single(30,62,50,61,27,94,102,86,64,29,49 ))  : ?>
~ ad code goes here ~
<?php endif; ?>

this doesn’t work at all – returns blank page:

<?php if( !is_single( array( 30,62,50,61,27,94,102,86,64,29,49 ) )  : ?>
~  ad code goes here ~
<?php endif; ?>
