Following up after what pageoneresults wrote, there is a possibility that Google tries to parse domain names. However, even if they do so now, no guarantee that they will in the future. Thus, assuming the hyphen is is needed is good strategy. As for whether lots of hyphens can hurt, given domain names like this tend to be correlated with spammy sites this is risky. IOW, don't overdo it.
