Dont use objectManager directly to retrieve these objects is not the recommended way.
Instead, you should use dependency injection to get an instance of

\Magento\Framework\Registry or \Magento\Framework\RegisterInterface in your class constructor.

public function __construct(
...,
\Magento\Framework\Registry $registry,
...
) {
$this->registry = $registry;
...
}

$this->registry->register('my_value', 5);

$this->registry->registry('my_value');
Example
$this->registry->registry('current_product');
$this->registry->registry('current_category');
$this->registry->registry('current_cms_page');
