Thanks.  That worked.   Here's my code:

module hashtools;
import std.conv;
import std.digest.md;

string uintSliceToHash(const uint[] slice) {
     auto  md5 = new MD5Digest();
     md5.put(slice.to!(ubyte[]));
     return md5.finish().to!(string);
}

unittest {
     import std.stdio;
     uint[] slice = [1,2,3,4];
     writeln(uintSliceToHash(slice));
}
