For any term a(n), all numbers of the form a(n)*10^3k, k >= 0, are in this sequence. We could call "primitive" the terms not of this form, i.e., those without trailing '0'.
FORMULA
a(n) = A294999(n)^3.
EXAMPLE
2197 is in the sequence because it is a cube, 2197 = 13^3, and its largest digit is 9.
PROG
(PARI) for(n=1, 150, vecmax(digits(n^3))==8 &&print1(n^3, ", "))
