456,790,123

[Math.]  Multiples of 012345679 by 1, 10, 19, 28, 37, 46, 55, 64 and 73 yield all 9 rotations of the number itself: 012345679, 123456790, 234567901, 345679012, 456790123, 567901234, 679012345, 790123456 and 901234567. All numbers are missing digit 8.

457,831,609

[Math.]  213972 = 457,831,609, a square using all 9 digits 0-9 once, except digit 2.

459,165,024

[Math.]  459,165,024 = (4+5+9+1+6+5+0+24)5 = 545.

459,630,721

[Math.]  214392 = 459,630,721, a square using all 9 digits 0-9 once, except digit 8.

456,790,123

Math.]  012345679 is the 9-digit period of the rational number 1/81 = 0.012345679012345679… or 0.012,345,679.

Multiples of 012345679 by 1, 10, 19, 28, 37, 46, 55, 64 and 73 yield all 9 digit-rotations of the number itself: 012,345,679, 123,456,790, 234,567,901, 345,679,012, 456,790,123, 567,901,234, 679,012,345, 790,123,456 and 901,234,567. All numbers are missing digit 8.

Multiples of 012345679 by a number from 1 to 80 of the form x (mod 9), where x = 1, 2, 4, 5, 7 or 8, will yield a 9-digit number, including all but one digit from 0 to 9. The missing digit is (9–x), again taking only values: 8, 7, 5, 4, 2 or 1. (Adding extra 0 to any 8-digit numbers). Its multiple by 81 is 999,999,999.

xyz,abc,def

[Math.]  For any xyz = 100 to 999, there are always six 6-digit numbers abc,edf such that the sum (xyz+abc,def) is equal to one of 6 digit-rotations of 142,857 and the number  xyz,abc,def is a multiple of 142,857.

For any xyz = 100 to 999, there are always twelve 6-digit numbers abc,edf such that the sum (xyz+abc,def) is equal to one of 12 digit-rotations of 076,923 or 153,846 and the number xyz,abc,def is a multiple of 76,923.
