You'd have to have to save the estimates AFTER 
applying -check-. Thus, type

 reg y x*  w1 w2
 check
 est store regr1
 est table regr1 , stats(N myp)

Have you seen -estadd- (ssc d estadd)? With -estadd- 
you could do things such as

 program define estadd_check, eclass
   testparm x*
   ereturn scalar myp=r(p)
 end

 reg y x* w1
 est store regr1
 reg y x* w1 w2
 est store regr2
 estadd *, s(check)
 est table *, stats(N myp)
