Check Digit Verification of cas no

The CAS Registry Mumber 104615-58-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,6,1 and 5 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 104615-58:
(8*1)+(7*0)+(6*4)+(5*6)+(4*1)+(3*5)+(2*5)+(1*8)=99
99 % 10 = 9
So 104615-58-9 is a valid CAS Registry Number.

Synthesis, structure, and photoluminescence of 5-phenyl-2-pyridyl-5,6- dihydro[1,2,4]triazolo[1,5-c]quinazolines

Gusev, A. N.,Shulgin, V. F.,Topilova, Z. M.,Meshkova, S. B.

, p. 95 - 98,4 (2020/09/16)

The reactions of salicylaldehyde and benzoic aldehyde with 5-(2-aminophenyl)-3-pyridyl-1?-1,2,4-triazoles were studied. The reaction products are 5-phenyl-2-pyridyl-5,6-dihydro[1,2,4]triazolo[1,5-c]quinazolines. The structures of the synthesized compounds were determined by IR spectroscopy and 1? and 13? NMR spectroscopy. The luminescence properties of solutions and solid samples were studied.
