Former capital of Moldavia is excellent to go around (4)

I believe the answer is:

iasi

I'm a little stuck... Click here to teach me more about this clue!

'former capital of moldavia' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'is excellent to go around' is the wordplay.
'excellent' becomes 'ai' (resembles 'A1', old-fashioned term for excellent).
'to go around' says the letters should be written in reverse (I've seen 'going around' mean this).
'is'+'ai'='isai'
'isai' backwards is 'IASI'.

Can you help me to learn more?
