Valid un-stamped Dutch tourist visa, do I need Airport Transit Visa (ATV) for France? - Pakistan Passport [duplicate]

So I already have a valid Schengen tourist visa issued from Dutch embassy on my valid Pakistan passport. However, I have not yet traveled on it to Holland so it is still un-stamped by the immigration in Holland.

Now I have to make a trip to US through Air France (tickets purchased). Since I will be transiting through Paris CDG, will I need to apply for a separate Airport Transit Visa for Paris,France?

My understanding is that a new Schengen tourist visa is not issued (from other Schengen nation) as long as there is a valid Schengen tourist visa from another state. Is this also applicable in case of Transit Visa?
