390

Correcting: The digits to be 0,1,2,3,4,5,6 & 7

For 4 digit numbers,
unit's place must be 0 or 5 i.e. 2 possibilities
=> In ten's place,7 possibilities
=> In hundred's place,6 possibilities
=> In thousand's place,5 possibilities
=> 2*7*6*5 = 420 numbers

Eliminating the numbers having 0 as first digit
i.e. 6*5 = 30 numbers

=> 420 - 30 = 390 numbers
