Be aware the following from that website:
I am not a lawyer. I have no legal training. Please, if in doubt, be sure to use the services of a professional lawyer whom you trust.

According to most site I have seen, A# of OPT is not the Alien Registration Number, therefore, not suggested to put OPT A# on the forms.
