No. The Missouri Compromise of 1820 allowed slavery in those parts of the Louisiana Purchase that were South of the line. North of the line, it was illegal. This simple and sensible compromise kept the peace for thirty years.
The Missouri Compromise itself (1820). Also the very last compromise attempted before the outbreak of war (Crittenden) proposed that the Missouri Line could be re-established and extended all the way to the Pacific. It was this compromise that Lincoln rejected, because it could have allowed some extension of slavery.
The Missouri Compromise was nullified by the new Compromise of 1850 - caused by the admission of California, which extended a long way on either side of the Missouri line, and rendered it obsolete.
