Chain length in inches is approximately chain stay length (measured between axle and bottom bracket centers), multiplied by 2 (top and bottom), plus big ring tooth count / 4 (it wraps about half the ring, and 1" pitch chain has two half lengths with matching teeth per inch), plus big cog count / 4, plus an inch for the derailleur.
Multiply by 2 to get the half-link count which is how chain makers count.

With an online chain calculator, I got 56 links (112 pitches) with 60x23 and a 410 chain stay. And yes, 1" is the minimum a derailleur needs. If you google "chain length calculator" you can play with the numbers directly.
And for what it is worth, with a 1x9, you will need as means to keep the chain from falling off the crank sprocket. I know from first hand experience. You didn't ask, but figured I'd offer.
