In the framework of SO(10) gauge unification and the seesaw mechanism, weshow that the upper bound on the mass of the heaviest right-handed neutrino$M_{R_3} < 3 \times 10^{11}$ GeV, given by the Pati-Salam intermediate scale of$B-L$ spontaneous symmetry breaking, constrains the observables related to theleft-handed light neutrino mass matrix. We assume such an upper limit on themasses of right-handed neutrinos and, as a first approximation, a Cabibbo formfor the matrix $V^L$ that diagonalizes the Dirac neutrino matrix $m_D$. Usingthe inverse seesaw formula, we show that our hypotheses imply a triangularrelation in the complex plane of the light neutrino masses with the Majoranaphases. We obtain normal hierarchy with an absolute scale for the lightneutrino spectrum. Two regions are allowed for the lightest neutrino mass $m_1$and for the Majorana phases, implying predictions for the neutrino massmeasured in Tritium decay and for the double beta decay effective mass$|<m_{ee}>|$.
