Check Digit Verification of cas no

The CAS Registry Mumber 162664-91-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,2,6,6 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 162664-91:
(8*1)+(7*6)+(6*2)+(5*6)+(4*6)+(3*4)+(2*9)+(1*1)=147
147 % 10 = 7
So 162664-91-7 is a valid CAS Registry Number.

Synthesis and Properties of Nonsymmetric Dinaphtodibenzoporphyrazine Complexes with D(2h) symmetry of the Ligand

Nemykin, V. N.,Subbotin, N. B.,Kostromina, N. A.,Volkov, S. V.,Luk'yanets, E. A.

, p. 1141 - 1145 (2008/10/08)

Nonsymmetric metal-free phthalocyanines, as well as copper and monolutecium complexes with D2h symmetry of the ligand that contain two tetraphenylisoindolyl and tert-butylbenzisoindolyl fragments are prepared upon the interaction of two different dinitriles, one of which provides sterichindrance for a template synthesis of a macrocycle. Molecular asymmetryis shown to affect electronic absorption and EPR spectra of the compounds synthesized.
