Check Digit Verification of cas no

The CAS Registry Mumber 289049-62-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,9,0,4 and 9 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 289049-62:
(8*2)+(7*8)+(6*9)+(5*0)+(4*4)+(3*9)+(2*6)+(1*2)=183
183 % 10 = 3
So 289049-62-3 is a valid CAS Registry Number.

Supramolecular ensembles based on the donor-acceptor interactions of porphyrins

Pukhovskaya,Guseva, L. Zh.,Semeikin,Golubchikov

, p. 135 - 141 (2011)

Dimeric and trimeric supramolecular structures were synthesized on the basis of donor-acceptor interactions of manganese(III) and tin(IV) complexes of 5,15-diphenyl-3,7,13,17-tetramethyl-2,8,12,18-tetrabutylporphyrin with 5-(4a€-oxyphenyl)-15-phenyl-3,7,13,17-tetramethyl-2,8,12, 18-tetrabutylporphyrin. The structure of the compounds was studied by NMR spectroscopy and TLC.
