[jira] [Commented] (VALIDATOR-422) ISINCheckDigit.ISIN_CHECK_DIGIT.isValid give wrong answer for some code

    [ https://issues.apache.org/jira/browse/VALIDATOR-422?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15982656#comment-15982656 ] 

Sebb commented on VALIDATOR-422:
--------------------------------

The CheckDigit routines only validate check digits.
If there are other requirements (such as a length), these must be dealt with separately.

For example, ISSNCheckDigit handles the checkdigit validation and ISSNValidator handles the overall validation.
However there is currently no ISINValidator class.

> I use "ISINCheckDigit.ISIN_CHECK_DIGIT.isValid" to check whether a code is ISIN.  But wrong result found during my test.  For example "3133EHHF3" can pass the check while it is apparently not an ISIN code.
