This is not a crossword - Sudoku

Normal Sudoku rules apply. (Place the digits 1-9 in every row, column and 3 by 3 box such that no digit repeats in each row, column, or box.) Shaded squares indicate even digits. Not all shaded squares are provided. You may enter in digits for filled in 3 square rows or columns if 3 digits are provided (in that order).
