  We study the baryogenesis via lepton number violation in the model of
Anti-GUT. The origin of the baryogenesis is the existence of right-handed
Majorana neutrinos which decay in a C, CP and lepton number violation way. The
baryon number asymmetry is calculated in the extended Anti-GUT model which is
only able to predict order of magnitude-wise. We predicted baryon number to
entropy ratio, Y_B=1.46{+5.87\atop-1.17}\times10^{-11}, and this result agrees
with experimental values very well.
