Maybe by creating all available CRS and checking each created CRS...if it's
equal to the CRS created by WKT.
This will create an array with all available CRS:

>
> int maximum = 1;
>
> if (cache == null) {

> CRSAuthorityFactory crsfactory =

> Set codes = crsfactory.getAuthorityCodes();
>
> maximum = codes.size();
>
> ArrayList list = new ArrayList(maximum);
> Iterator it = codes.iterator();
>
> while (it.hasNext()) {
>
> String str = (String)it.next();
>
> if (str.startsWith("EPSG:")) {
>
> str = str.substring(5);

>
> try {

Check if there's any EPSG code that matches the same definition:
CoordinateReferenceSystem crsWKT = createCRSbyWKT(SOURCE_WKT);
> for (int i=0; i < cache.length(); i++){
> if(cache[i].getName().equals(crsWKT.getName())){
> // Match!!!
> }
> }

Something like that....
