Check Digit Verification of cas no

The CAS Registry Mumber 55775-16-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,7,7 and 5 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 55775-16:
(7*5)+(6*5)+(5*7)+(4*7)+(3*5)+(2*1)+(1*6)=151
151 % 10 = 1
So 55775-16-1 is a valid CAS Registry Number.

Hydropyrenes, Alicyclic Model Compounds for GC-MS Investigations

Mann, G.,Sicker, A.,Herzschuh, R.,Engewald, W.,Praefcke, K.

, p. 267 - 272 (2007/10/02)

Hydrogenation of asymmetric and symmetric hexahydropyrene gives the five possible aromatic decahydropyrenes via different octahydropyrenes.From these compounds some dodecahydro- and tetradecahydro-pyrenes, the four isomers of perhydropyrene with chair conformations and five new stereoisomers with twist boat six-membered rings are obtained.The configurations of the hydrogenated pyrenes are assigned using chromatographic retention indices and mass spectrometric fragmentation in combination with force field calculations.
