CGS Unit of Planck's Constant h is
"erg"cdot s

Explanation:

Planck's Constant h is a physical constant.

It has a value of 6.6261 xx 10^-27 cm^2 gm s^-1 in CGS units and 6.6261 × 10^-34 m^2 kg s^-1 in SI units.

As your question is in CGS system of units, we will use these only.

The famous equation E=hxxnu
Where E is the energy of a quantum of light.
nu is its frequency.
Lets us write units of all the known quantities
Unit of Energy is: erg
Unit of frequency is: Hz or s^-1
E=hxxnu
"erg"="unit of "hxxs^-1, solving for 'unit of h'

"unit of "h="erg"/s^-1="erg"cdot s
