Check Digit Verification of cas no

The CAS Registry Mumber 137126-07-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,1,2 and 6 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 137126-07:
(8*1)+(7*3)+(6*7)+(5*1)+(4*2)+(3*6)+(2*0)+(1*7)=109
109 % 10 = 9
So 137126-07-9 is a valid CAS Registry Number.

SYNTHESIS, SPECTRAL-LUMINESCENCE, AND ACID-BASE PROPERTIES OF 3-FLUORO-7-DIALKYLAMINOCOUMARINS

Gordeeva, N. A.,Kirpichenok, M. A.,Patalakha, N. S.,Khutoretskii, V. M.,Grandberg, I. I.

, p. 491 - 495 (1991)

The corresponding 3-fluoro-substituted coumarins were obtained by reactions of 7-diethylaminocoumarin, 2,3,6,7-tetrahydro-1H,5H-quinolizinocoumarin, and 2,3,6,7-tetrahydro-9-methyl-1H,5H-quinolizinocoumarin with XeF2, FClO3 or N-fluoropyridinium tetrafluoroborate.A strong mesomeric effect of the fluorine atom on the 7-amino group was established as a result of a study of the absorption and fluorescence spectra and the acid-base properties of the synthesized compounds.
