Try this:

Note: $eavSetupFactory should be an instance of  Magento\Eav\Setup\EavSetupFactory class, so add it to your constructor as a dependency.
/** @var Magento\Eav\Setup\EavSetup $eavSetup */
$eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);

if(!$eavSetup->getAttributeId(\Magento\Catalog\Model\Product::ENTITY, 'attr_code')) {
    //Create the attribute
}

This will attempt to retrieve the attribute ID for the attribute with the code attr_code. If it returns a falsey value, the attribute does not exist.

Write a shell script
Create a product Collection which give list products which have regnum fields
group this collection by grouByAttribute('regnum')

require '[Your_Magento_DIR]/app/Mage.php'; Mage::app("admin"); umask(0); $collection=Mage::getResourceModel('catalog/product_collection'); $collection->addAttributeToSelect('renum'); $collection->groupByAttribute('renum'); $renumValues=$collection->getColumnValues();

Magento2 – Check if Product Attribute Value is Null

I assume you just want to see if the data is set against the product before echoing it?

This will depend on if you are getting a collection of products, adding the attribute to select and then looping through them / if you are just on a product page, but the following should work:

<?php if ($block->getProduct()->getPriceRange()): ?>
 //Do things here
<?php endif; ?>
