Check Digit Verification of cas no

The CAS Registry Mumber 5602-69-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,0 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5602-69:
(6*5)+(5*6)+(4*0)+(3*2)+(2*6)+(1*9)=87
87 % 10 = 7
So 5602-69-7 is a valid CAS Registry Number.

Conformational and configurational behaviour of κ-agonistic 3,7-diazabicyclo[3.3.1]nonan-9-ones - Synthesis, nuclear magnetic resonance studies and semiempirical PM3 calculations

Siener, Tom,Holzgrabe, Ulrike,Drosihn, Susanne,Brandt, Wolfgang

, p. 1827 - 1834 (2007/10/03)

2,4-Diaryl substituted 3,7-diazabicyclo[3.3.1]nonan-9-one 1,5-diesters were found to have a high affinity for κ-opioid receptors. To develop highly potent analgesics, the purpose of this study was the synthesis and the structural characterisation of the novel 2,4-bis(4-nitrophenyl), 2,4-bis(3-nitrophenyl), 2,4-bis(4-quinolyl), 2,4-bis(2-quinolyl), 2,4-bis(1-naphthyl) and 2,4-bis(2-naphthyl) substituted 3,7-diazabicyclo[3.3.1]nonan-9-one 1,5-diesters by means of NMR spectroscopy and molecular modelling. It could be proved that several derivatives undergo trans-cis-isomerisation of the aromatic rings linked to the rigid skeleton whereas others show rotational isomerisation. Semiempirical quantum-chemical PM3 calculations were performed to analyse the thermodynamic stability of the isomers as well as the mechanism of the trans-cis-or cis-trans-conversion.
