Check Digit Verification of cas no

The CAS Registry Mumber 81568-58-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,5,6 and 8 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 81568-58:
(7*8)+(6*1)+(5*5)+(4*6)+(3*8)+(2*5)+(1*8)=153
153 % 10 = 3
So 81568-58-3 is a valid CAS Registry Number.

Benzocyclobutenes. Part 7. Synthesis and X-ray Crystal Structure of Cyclobutaphenanthrene-1,2-dione and the Synthesis of Hexabenzotriphenylene

Hacker, Nigel P.,McOmie, John F. W.,Meunier-Piret, Jacqueline,Meerssche, Maurice Van

, p. 19 - 24 (2007/10/02)

Photocycloaddition of tetrachloroethene to phenanthrene gives 1,1,2,2-tetrachloro-1,2,2a,10b-tetrahydrocyclobutaphenanthrene.Treatment of this compound with N-bromosuccinimide gives the corresponding tetrachlorodihydrocyclobutaphenanthrene which can be hydrolysed to cyclobutaphenanthrene-1,2-dione.The 1H and 13C n.m.r. spectra and X-ray molecular structure of the dione have been determined.Flash-vacuum pyrolysis of the dione gives a low yield of hexabenzotriphenylene.
