[seqfan] Add "touching" digits of "n"

[Eric Angelini]

Hello SeqFans,
I think integers like those should deserve a seq.:

80, 107, 910, 1102, 1459, 41358, ...

When you add two "touching" digits of "n", the result 
is visible in "n".

Example:
80 --> 8+0=8
107 --> 1+0=1  /  0+7=7
910 --> 9+1=10  /  1+0=1
1037 --> 1+0=1  /  0+3=3  /  3+7=10 
1459 --> 1+4=5  /  4+5=9  /  5+9=14
41358 --> 4+1=5  /  1+3=4  /  3+5=8  /  5+8=13

Best,
É.
