How to dequeue style scripts?

I want to change the behavior of drop down menu and need to replace the script. But I can not dequeue it.

This code:

add_action( 'wp_enqueue_scripts', 'dequeue_unnecessary_scripts' );
function dequeue_unnecessary_scripts() {
	wp_dequeue_script('woocs-style-1-js');
}

doesn’t work for this line:

<script type='text/javascript' src='http://example.com/wp-content/plugins/woocommerce-currency-switcher/views/shortcodes/styles/style-1/actions.js?ver=2.3.5' id='woocs-style-1-js'></script>
