specific Number range from a set of available number ranges - logic

Hi,

I have a range with me in one work area like 60000130 to 60000140.

In one more internal table I have data like 90000130 to 90000134

60000130 to 90000400

80000130 to 80000134

20000130 to 20000134

10000130 to 10000134

Any better logic to search whether the given work area is there in the internal table or not.

Thanks
