How does Google detect a domain's whois information?

Recently I just opened a new account at name.com,then I found I can have numerous sub accounts there.It's great if you want to manage lots of domains and hope them have different whois information.I need that because I want my sites can link each other to pass link juice in order to get higher rankings in Google.So I regsistered a new domain and planed to push it to a sub account with different information from the main account.Then I found that I need to wait 5 days before I can push a new domain to sub account.I hate that rule.My question is,will Google know/remember the whois information of my main account?That's important,because I have domains in that account and I planned to link the domain in sub account to the domain in main account.

I have heard that whois information can be hided by paying small amount. You can do that. And the system which you trying to employ is called 'link wheel' or 'link cycle'. But if Google detects that it may penalize all your websites. So try other backlink building methods.
