Hi,

I have a requirement which i need help

1) i have a email-to-case where once a case gets created in salesforce i need to verify if there is any credit number present and if so i need to make a custom checkbox on case to true based on it i need to show a pop up message on lightning action saying that this case is having credit card number

i tried using workflow regex function but if i enter any number like 012 its making the checkbox to true automatically, please let me know how can i achieve it in salesforce

Thanks in advance
