Replace the first number in three groups only

Hi experts
There is a string "12546-10203-32198-98876-100047"

These are 5 groups, I wanted to replace the first number of the three groups in the middle only with conditions
0 = A
1=D
2=Z
3=K
4=M
5=X
6=C
7=S
8=Q
9=F

so the result of the example string should have be
12546-D0203-K2198-F8876-100047

Thanks a lot for this big help

HI
It is a very nice piece of code
But I Believe that splitting one thing 4 times is time consumption
so I suggest this amendment to you code
Do you agree ?
No offence though

only when the first charcter is numeric.

@jindon
Your code adds the letter and didn't remove the number (The number should be replaced)
12546-D0203-K2198-F8876-100047
