Check Digit Verification of cas no

The CAS Registry Mumber 4090-99-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,9 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4090-99:
(6*4)+(5*0)+(4*9)+(3*0)+(2*9)+(1*9)=87
87 % 10 = 7
So 4090-99-7 is a valid CAS Registry Number.

Expanded campestarene hosts for tetra- and dinuclear uranyl(VI) complexes

Chaudhry, Mohammad T.,Lelj, Francesco,MacLachlan, Mark J.

supporting information, p. 11869 - 11872 (2018/12/01)

The first expanded campestarenes based on a keto-enamine scaffold have been constructed using uranyl acetate as a template. Macrocycles with six and eight aryl rings in their backbone host dinuclear and tetranuclear uranium(vi) species, respectively. The complexes were characterized by SCXRD, FT-IR, UV-vis, and NMR spectroscopy, and DFT calculations corroborated their structures.
