Is possible add class for last post of Custom Post Type?

Question

I need to add a different class for last post of a Custom Post Type. Is it possible?

I have found this code, but it works only in posts

function wpc_last_post_class( $classes ) {
    global $wp_query;  
    if(($wp_query->current_post+1) == $wp_query->post_count) $classes[] = 'last'; // change the class name  you would like to add here  
    return $classes;  
}  
add_filter('post_class', 'wpc_last_post_class');

Not exactly what you asked for, but given that classes are primarily used for styling, might you consider using CSS pseudo-class ":last-child" instead of PHP code?

Here's some information on how to style using :last-child
