Verify an entity is translated
Actually if you are doing field translation then there is no point of having translate now link at Node level. For this there is always translate primary tab for this. see in screenshot. 

Still if you want to achieve this functionality, loop through this array within node object. 

$node-&gt;translations-&gt;data


Do this in module file in hook_preprocess_HOOK here it will be hook_preprocess_node and pass a variable to node.tpl.php
