Dear Friend,
To my knowledge there is no such option to check PAN card details with help of PAN number ( I am not sure may be I am wrong). Earlier I used to check name of the Pan card holder with help of pan number thru net but I could not trace now how to check the same.
But we can check the pan cad number with help of card holder details like surname, middle name, last name and date of birth.
please go thru this

I wish you all the best.
