How to check pan card is linked with bank account?

The easiest way is using your bank's net banking. You should log in to your account online. Go to the profile or account settings section. Then look for your 'KYC Details'. If your PAN is linked, you will see the number there. The mobile banking app often has this information too. If you can't find it online, you can always visit your bank branch and ask them to check your KYC status for you.
