Split numbers and split words

How do I split numbers!

I have two problems/challenges!

Part I...
I got the answer 1987, and now I want Excel to take the numbers out and display...
1 in one box then i set + in the next, then 9 in the 3ed. box, next box +, then 8, then +, then 7 in the last so that i can have Excel make a SUM of it all to 25.

How do I split 1987 and put the numbers in different boxes?

Part II...
I want to make A=1 B=2... all the way up to 9, then start over again with J=1 K=2... up to 9 again and then over again.

So that if I write my name it comes out as a value of 14 (Odd = O=6 D=4 D=4 =14)

(AJSØ=1 BKTÅ=2 CLU=3 DMV=4 ENW=5 FOX=6 GPY=7 HQZ=8 IRÆ=9, It's the Norwegian alphabet, that's why there are some extra letters)

So how do I set up my Excel so that is ANY name is typed in I can get it out into a number from the values assign?
