Check Digit Verification of cas no
The CAS Registry Mumber 6404-76-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,0 and 4 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6404-76:
(6*6)+(5*4)+(4*0)+(3*4)+(2*7)+(1*6)=88
88 % 10 = 8
So 6404-76-8 is a valid CAS Registry Number.

Syntheses of 3-Acyl-4-hydroxy-2(1H)-quinolones
Kappe, Thomas,Aigner, Rudolf,Hohengassner, Peter,Stadlbauer, Wolfgang
, p. 596 - 601 (2007/10/02)
3-Acyl-4-hydroxy-2(1H)-quinolones 5 are obtained by hydrolytic ring opening and subsequent decarboxylation from the corresponding pyranoquinolin-2,5(6H)-diones 4, which in turn are easily obtained from 1:2 condensation of of anilines 1 with diethyl malonate 2a or 1:1 condensation of diethyl alkyl- or arylmalonates 2b-e with 4-hydroxy-2(1H)-quinolones 3.Nitropyranoquinolinediones 6 furnish after ringopening 3-nitroacetyl-4-hydroxy-2(1H)-quinolones 8.Pyranoquinolines 7 and 9 with acetyl- or aminosubstituents are hydrolyzed during basic ringopening to yield 5.
