Can you replace each alphabet with the number (1 - 9) to make below equation correct ?

AB * C = DE - F = GH / I

39 * 1 = 45 - 6 = 78 / 2

AB - C = DE / F = GH * I can be solved as
A = 3
B = 9
C = 1
D = 4
E = 5
F = 6
G = 7
H = 8
I = 2

So below equation can be solved as:
AB - C = DE / F = GH * I
39 * 1 = 45 - 6 = 78/2
39 = 39 = 39.
