Issue in reCaptcha Validation

when we entered extra letter after the correct reCaptcha code, it is validating as correct example: image values: 147 789523 i entered the values like: 1478 789523 another example with alphabet words: image values: qwer wsdgtrf i entered the values like: qwerg wsdgtrf For the above both the cases reCaptcha service has responded as correct.Please suggest.
