Check Digit Verification of cas no

The CAS Registry Mumber 1312999-45-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,2,9,9 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1312999-45:
(9*1)+(8*3)+(7*1)+(6*2)+(5*9)+(4*9)+(3*9)+(2*4)+(1*5)=173
173 % 10 = 3
So 1312999-45-3 is a valid CAS Registry Number.

Trigonal rigid triphenols: Self-assembly and multicomponent lattice inclusion

Moorthy, Jarugu Narasimha,Natarajan, Palani,Bajpai, Alankriti,Venugopalan, Paloth

, p. 3406 - 3417 (2012/04/04)

The sterics introduced via methyl groups impart rigidity and inclusion behavior to trigonal C3-symmetric triphenol hosts H1-H4. Triphenol H1 is found to mimic the O-H...O hydrogen-bonded self-assembly of trimesic acid to yield porous honeycomb nets. It is found that 18-crown-6?H1 in turn binds guest molecules in the hexagonal voids to yield guest?guest?host multicomponent molecular crystals. The triphenol H2 and the homologous derivatives H3 and H4 are also found to crystallize with 18-crown-6 and other guests to yield multicomponent crystals, but in these cases the 18-crown-6 is found to serve as a spacer. While the structure of H2 is determined in its guest-free form, some of the inclusion compounds of triphenols lend themselves to crystal packings that are deciphered based on network topologies. The networks observed for H1-Tol and H3-C-B-Et are unique; in the latter, the crystal packing analysis reveals organization of molecules into a pattern that is reminiscent of borromean rings.
