Google adsense verification code

<script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
<script>
(adsbygoogle = window.adsbygoogle || []).push({
google_ad_client: "cx-pub-0xxxxxxxx",
enable_page_level_ads: true
});
</script>

Hell,i want to verify my site for google adsense.

I have used hook element and add code inside the Header section of the site.

Please see the screenshot - https://www.screencast.com/t/wLqGIcaCXtmH

Have I done this correctly?Do I need to make any change for the verification process?

Thank you
