%N Primes p such that sum of all primes less than or equal to p is pandigital (includes all 10 digits at least once).

%C A049443 is a subset of this sequence.

%e a(15) = 519947 because 2 + 3 + 5 + 7 + 11 + ... + 519947 = 10689537247 which is pandigital.

%t b = {}; a = 0; Do[a = a + Prime[i]; u = Union[IntegerDigits[a]]; If[Equal[u, {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}], AppendTo[b, Prime[i]]], {i, 1, 60000}]; b

%Y Cf. A049443, A228468.
