Firstly I don't care about your warnings.Secondly you have to use this 
 https://en.wikipedia.org/w/index.php?title=Special%3ABookSources&isbn;=9789994303656+ 
 which is provided by Wikipedia.The fact that a website (as it says:This website is an independent service and is not affiliated with The International ISBN Agency Limited or any other national ISBN registration agency)doesn't mean it is not a correct ISBN..So your claim that it isn't recognised by the ISBN system is a false claim.
