regex

I want to create the regular expression in javascript which will check the valid conditional string like

-1 OR (1 AND 2) AND 1

-1 OR (1 AND 2)

-1 OR 2

-1 OR 1 OR 1

-1 AND 1 AND 1

The string should not contain 'AND' and 'OR'. For example - 1 OR 2 AND 3 is invalid. -It should be (1 OR 2) AND 3 or 1 or (2 AND 3).

I tried the following Regex. It works for most of the conditions but it is failing to check the above condition.

/^(\s*\(\d+\s(AND|OR)\s\d+\)|\s*\d+)((\s*(AND|OR)\s*)(\(\d+\s(AND|OR)\s\d+\)|\s*\d+))*$/

Can anyone please help me to sort out the above problem.
