Regex combination

Is it possible in regex to combine two validations? Whenever a series of 8 digit numbers(12345678) are given in a statement along with space(1234 5678) Regex should throw an error. Along with validation for alphabets &other special character .

Eg: 1234 apartment ,#23building state 234 456 (valid one)

1234 apartment ,#23building state 1234 5678 overhill (invalid one because of series/continuous of 8 digits)

677 flat, @(23) floor, up state 56789123 state UK ( invalid because of continuous 8 digits)
