Check Digit Verification of cas no

The CAS Registry Mumber 39054-97-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,0,5 and 4 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 39054-97:
(7*3)+(6*9)+(5*0)+(4*5)+(3*4)+(2*9)+(1*7)=132
132 % 10 = 2
So 39054-97-2 is a valid CAS Registry Number.

Synthesis and Structural Analysis of the Bridged peri-Naphthalene: 1,3-Dihydro-2-phenalenone

Joergensen, Flemming S.,Thomsen, Tove

, p. 113 - 116 (2007/10/02)

The synthesis of the peri-naphthalene, 1,3-dihydro-2-phenalenone is reported in detail.The molecular structure is calculated by molecular mechanics to be a folded Cs conformation with the carbonyl group placed out of the main plane of the molecule.Photoelectron spectroscopy and MNDO molecular orbital calculations indicate the naphthalene and carbonyl moieties to appear as isolated units without appreciable intramolecular interactions in accordance with a folded conformation.
