COMMENTS
The first digits sums are given in A119945.
Umlaute are taken as ``ae'' (not appearing), ``oe'', ``ue'' and ``sz'' (scharp s) (like in the German name for ``30'') as ``ss'' (not "sz").
EXAMPLE
``Null'' in German for the number 0 has first digit sum
59=A119945(0). Therefore the next digit sum becomes 5+9=14 and finally
1+4=5, hence a(0)=5.
