AI Summary

Check digit ensures GST migration ARNs are validated to detect common input errors and preserve data integrity.
A check digit is a single digit computed by an algorithm from the other characters in an Application Reference Number to enable error detection when the ARN is input or transmitted; it detects common input mistakes (such as a mistyped digit or certain adjacent transpositions) and supports validation during manual or automated processing without encoding substantive transactional data.
