A concurrent thread touches on pertinent issues. 
Also, there is a longer discussion in Stata Journal 
2(3), 314-329 (2002). 

In that thread I urged the merits of keeping ids as 
string, although much depends on the details.

In this case, 

. gen str1 newid = "" 
. replace newid = string(id, "%12.0g") + "51" 

Naturally you could try it as a numeric operation: multiply by 100 
and add 51, but to keep precision in all digits, make sure the 
result is put in a -double- or -long-.
