You are right, and checked back, La Defense -> Chatelet is 9.4km (that's the two RER stations left open after shutting down CDG Etoile and Auber. And they basically shut down anything between these stations)

They shut down 36 stations in total at the peak of the demos: https://www.lavoixdunord.fr/502926/article/2018-12-07/la-rat...

My bad, didn't realise there were so many stations shut down.

I travelled without any hassles on those days so I assumed just a couple of main stations were closed.
