My first published regular Sudoku.
All I have to say is normal sudoku rules apply and good luck!
Solution code: Row 7, Column 8 (18 digits, no spaces)

I had not a single idea on how to continue after the first few digits found their way into the grid. But then ...
I remembered: "_every_ good sudoku has a ..." :)
So, there was in a very logical way an other hidden given digit <grin>
Anyways it turned out to be right.
