  For the equations of the form $y''=P(x,y)+3 Q(x,y) y'+3 R(x,y) {y'}^2 +S(x,y)
{y'}^3$ the problem of equivalence in the class of point transformations is
considered. Effective procedure for determining the class of point equivalence
for the given equation is suggested. This procedure is based on explicit
formulas for the invariants.
