You can try this 

moment('16-jun-199', 'DD-MMM-YYYY',true).isValid())

Note: additional true flag for strict parsing. which tells moment to not to use wildcards and use exact match.

Moment's parser is very forgiving, and this can lead to undesired/unexpected behavior.

For example, the following behavior can be observed:

 moment('2016 is a date', 'YYYY-MM-DD').isValid() //true, 2016 was
 matched

As of version 2.3.0, you may specify a boolean for the last argument to make Moment use strict parsing. Strict parsing requires that the format and input match exactly, including delimeters.

moment('It is 2012-05-25', 'YYYY-MM-DD').isValid();       // true
moment('It is 2012-05-25', 'YYYY-MM-DD', true).isValid(); // false
moment('2012-05-25',       'YYYY-MM-DD', true).isValid(); // true
moment('2012.05.25',       'YYYY-MM-DD', true).isValid(); // false
