Jean-Marc Falcoz discovered those self-stuffable numbers (see the previous post about "Stuffable numbers" by Neil Sloane):
126 is a self-stuffable number as 126 will be opened in 1.2..6 and 1.2..6 will become 112266 – which is a multiple of 126.
I guess it is easy to prove that the sequence of self-stuffable numbers is infinite.
