How do I know if a text field corresponding to a number

I have a field in a table that is a text data type, but is used to enter a date in the format MMDDYY (I did not create it and I'm stuck with it). However, some people enter the text values in this field for whatever reason (I have no control over that). So, instead of enter 030213, they could enter COBR or TODAYS or something like that or same part number, the part of text such as COBR13.

I would like to know if it is possible to tell if there is any text in this field. Go, I thought would be to assess if the text in the field column / can be converted into a number valid, so if the value is 021312, the answer would be Yes. If the value is 12COBR, COBR or todays TODAY1, then the answer is no. Figure I could use the CASE function to choose...

Any help is appreciated...

Thank you...

Quick google search of "oracle determines if the column is numeric.
