Was most of the Louisiana purchase south of the Missouri compromise line?

Most of the Louisiana Purchase was located to the west of the Mississippi River and included areas both north and south of the Missouri Compromise line, which was established at latitude 36°30′. While a significant portion of the territory acquired in the Purchase was south of this line, particularly in what is now Arkansas and parts of Louisiana, the northern portions of the Purchase, including land that would become North Dakota and Montana, were above the line. Thus, the Louisiana Purchase encompassed land both north and south of the Missouri Compromise line.
