A computer science problem by Thành Đạt Lê

\[ \boxed{\phantom0}\ \boxed{\phantom0}\ \boxed{\phantom0}\ \boxed{\phantom0} \times 3 = \boxed{\phantom0}\ \boxed{\phantom0}\ \boxed{\phantom0}\ \boxed{\phantom0}\ \boxed{\phantom0} \]

Can we fill in the boxes with distinct digits so that the equation is satisfied?

\(\)
Clarification: The above equation represents a 4-digit number multiplied by 3 to produce a 5-digit number, so the leftmost box is non-zero on either side.
