Fix SEDOL | Calculate SEDOL Check Digit

A SEDOL (Stock Exchange Daily Official List) is a 7-character alphanumeric code that serves as the National Securities Identifying Number for all securities issued in Ireland and the United Kingdom.

A SEDOL consists of two parts:
• A six-character alphanumeric code
• A single check digit.

For example: 2936921 (Walmart)

On this page, you can either:
• enter a SEDOL without the check digit, or:
• enter a full SEDOL you would like to fix.

In both cases, a correct SEDOL will be calculated for you, if possible. Note that the result can be a non-existing SEDOL, since it is being calculated!
