Check Digit Verification of cas no

The CAS Registry Mumber 2748-28-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,4 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2748-28:
(6*2)+(5*7)+(4*4)+(3*8)+(2*2)+(1*8)=99
99 % 10 = 9
So 2748-28-9 is a valid CAS Registry Number.

Synthesis and structure of new 3-pyrazolinylcoumarins and 3-pyrazolinyl-2-quinolones

Traven,Manaev,Voevodina,Okhrimenko

experimental part, p. 1508 - 1515 (2009/10/01)

The reactions of substituted 3-cinnamoyl-4-hydroxycoumarins and 3-cinnamoyl-4-hydroxy-2-quinolones with different phenylhydrazines gave 3-hetaryl-1H-4,5-dihydropyrazoles. The product structures were studied by 1H NMR spectroscopy and mass spect
