1. The record, from the token's own metadata:
printf '%s' "$(curl -s https://scimatic.org/nft/articles/19.json | jq -r .canonical_record)" | sha256sum
2. The hash stored on chain (contentHash(19)):
curl -s https://rpc.scimatic.net -H 'content-type: application/json' \
-d '{"jsonrpc":"2.0","id":1,"method":"eth_call","params":[{"to":"0x0E596B4bb924937aA35D9b342A90347ed6F05eF8","data":"0xf3e0c2900000000000000000000000000000000000000000000000000000000000000013"},"latest"]}'
The two must be equal (the second with a 0x in front).
