No, it's 69352859712417

You got your number from (I guess) Richard Bean's posting:
http://www.chess-archive.com/ccc.php?art_id=240236

However, he corrected this in the following post:
http://www.chess-archive.com/ccc.php?art_id=298979

So the numbers up to 10 ply are:

 0:                  1
 1:                 20
 2:                400
 3:              8,902
 4:            197,281
 5:          4,865,609
 6:        119,060,324
 7:      3,195,901,860
 8:     84,998,978,956
 9:  2,439,530,234,167
10: 69,352,859,712,417
