With regard to A062237, I noted that it was finite and both Chuck Seggelin
and myself found the additional elements 3634992 and 43139968.
I submitted an update to NJAS:

%I A062237
%S A062237 
10,20,30,40,50,60,70,80,90,119,1236,19135,19144,261296,3634992,43139968
%C A062237 For a d-digit number with d >= 88, the sum and product of the 
digits together have fewer than d digits.  So every element of this sequence 
has 87 or fewer digits, hence it is finite.
%O A062237 0
%K A062237 ,base,fini,nonn,

I have programmatically verified that these are all of the elements, so the 
"full" keyword can
be added.
