1. There is a central carbon that is double-bonded to an oxygen.
2. This carbon bears two substituents:
   - A five-carbon chain that contains double bonds between C1 and C2 and between C3 and C4 (both in the Z configuration), terminating in a methyl group at C5 (i.e., a Z,Z-1,3-pentadienyl group).
   - A nitrogen (single-bonded to the central carbon) that is imine-linked (double bond without Z/E configuration specified) to a six-membered ring.
3. In this six-membered ring, designate the ring nitrogen (bearing one hydrogen) as position 1, followed by carbons 2, 3, 4, 5, and 6. The ring contains two double bonds: one between carbon 2 and 3 and another between carbon 5 and 6. The imine bond joins the external nitrogen to carbon 4 of the ring. Carbon 2 carries a single methyl substituent; no other ring substituents are present.
