CWR error: A V-ISAN check character doesn't match
What it means
A V-ISAN carries two check characters: one covers the ISAN itself, the other reaches through the version segment. The arithmetic doesn't come out, so a character in the audio-visual identifier is wrong.
How to fix it
Check it against the ISAN agency's record. If there is no V-ISAN, leave all of those fields blank.
