Albert Barnes Commentary 1 Chronicles 6:9

"and Ahimaaz begat Azariah, and Azariah begat Johanan," — 1 Chronicles 6:9 (ASV)

Ahimaaz was the father of Azariah - It must, apparently, be this Azariah, and not the son of Johanan mentioned in 1 Chronicles 6:10, who was high priest at the dedication of Solomon’s Temple. For Zadok, who lived into the reign of Solomon (1 Kings 4:4), cannot have been succeeded by a great-great-grandson. The notice in 1 Chronicles 6:10, which is attached to the second Azariah, must, beyond a doubt, belong properly to the first.
