How can I find a Checksum of a Docker Image

I'm using Docker 1.10.3.

Docker Image Specification v1.0.0 says there is an Image Checksum field in a Docker Image JSON Description, like:

"checksum": "tarsum.v1+sha256:e58fcf7418d2390dec8e8fb69d88c06ec07039d651fedc3aa72af9972e7d046b",

However, there is no such a field in the result of docker inspect <IMAGE>.

How can I get the checksum of a particular image?
