The digit A represent 7.

According to Divisibility rule for 8 last 3 digit should be divisible by 8 giving reminder zero, so "B" satisfies only with "2" (432/8=54).

And for 11, the difference of the sum of alternative digit should be zero or 11. To satisfy this condition "A" should be 7.

Thanks!!

Eight in a row,
with nowhere to go,
except for the two
who can jump straight through.

Eight out in front,
not one a runt.
Across the range,
to make a change.

By foot or by horse,
they stay the course.
Till the victory is won,
And the battle is done.
