Yeah - you find the internal part number for the device, open your connection to the company's AS/400 and query the MRP system to get the info screen for that item. Then you check the lifecycle and last buy fields, and verify that the box marked "RoHS certificate on file" is checked (well, this is a text-only 3270-based application so it's really an underlined X as opposed to an empty underline cell, but you get the picture).
Short of having that much infrastructure in your organization, I think the answer to that is "no".
