Check Digit Verification of cas no

The CAS Registry Mumber 1149053-99-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,9,0,5 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1149053-99:
(9*1)+(8*1)+(7*4)+(6*9)+(5*0)+(4*5)+(3*3)+(2*9)+(1*9)=155
155 % 10 = 5
So 1149053-99-5 is a valid CAS Registry Number.

Hexaquacobalt(II) bis-(5-hydroxy-7-methoxy-4-oxo-2-phenyl-4H-chromene-6- sulfonate) tetrahydrate

Li, Wu-Wu,Zhang, Zun-Ting

, p. m176-m178 (2008)

The title compound, [Co(H2O)6](C16H11O7S)2·4H2O, with cobalt(II) at the centre of symmetry, exhibits alternating hydro-philic and hydro-phobic regions. Hydro-philic regions are generated by O - H...O hydrogen bonds among sulfonate groups, involving solvent water mol-ecules and coordinated water mol-ecules; π-π stacking inter-actions assemble the flavone skeletons into columns which form the hydro-phobic regions. A three-dimensional network is built up from an extensive array of hydrogen bonds, π-π stacking inter-actions and electrostatic inter-actions between the cation and anion. As a salt of the sulfonated derivative of naturally occurring tectochrysin (5-hydr-oxy-7-methoxy-flavone), this compound offers enhanced solubility and potential biological activity over the natural product.
