Global 5500 First Officer reported the 'CG' identifier for the Dutch waypoint/NDB is not available in the aircraft's database.

Narrative

While completing our route verification we noticed that our route was more than 9000 miles too long. We were able to determine that the waypoint CG" from the uploaded flight plan was not in the correct position. I attempted to enter the correct "CG" only to get the notification that it wasn't in the database. I was able to determine that none of the "CG"s in the database were in the western hemisphere. There are 3 "CG"s in the database and they are all in the eastern hemisphere. One is in Kulob; Tajikistan and the other two are Gold Coast; Australia. The "CG" called Dutch by Cape Girardeau; MO (N37°15.20 W089° 42.00) is not in the database. I was able to create a temporary (pilot created waypoint) based on the position of the NDB to complete the flight as filed.Presently there is no NavData Alert regarding this NDB not being in the database from Rockwell/Collins. I suggest a NavData Alert be disseminated about this waypoint/NDB not being in the database. I recommend this NDB be added in the next Database Update."
