This document is still technically a part of the United States Code,
No, the Articles of Confederation are not part of the US Code. They were superseded by the current US Constitution. They are not law in any way shape or form, except perhaps as an occasional interpretive guide to the current constitution when in court cases we try to compare it to the current document to argue that the new language means something different.
Repeat: The Articles of Confederation are not part of the US Code.
