Chromebook Serial Number Decoder

How can I determine what my Chromebook serial number means? The serial should have information about when the device was produced, where it was produced, etc.. I know I can get these questions answered from the Chromebook itself, unfortunately very often I do not have access to the physical device, just the Serial.
