In my WebAPI i used the following:

        if (container.Length < 3 ||
            container.Length > 63 ||
            !Regex.IsMatch(container, @"^[a-z0-9]+(-[a-z0-9]+)*$"))
            throw new HttpResponseException(Request.CreateResponse(
                HttpStatusCode.BadRequest, "Invalid Request!"));
