You can attach an onClick client side JS function and then you can enable/disable the validator via JS.

<asp:CheckBox ID="" runat="server" OnClick="EnableDisable(this,ValidatorID)" />

<script type="text/javascript">
function EnableDisable(checkbox,ValidatorID){
  var myVal = document.getElementById(ValidatorID);
  ValidatorEnable(myVal, checkbox.checked); 
}
</script>

Try this:

<asp:RequiredFieldValidator ... Enabled=<%# checkBox.Checked %> ... />

Here, you have to set the AutoPostBack property value of the CheckBox to true.
