Check Digit Verification of cas no
The CAS Registry Mumber 59443-02-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,4,4 and 3 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 59443-02:
(7*5)+(6*9)+(5*4)+(4*4)+(3*3)+(2*0)+(1*2)=136
136 % 10 = 6
So 59443-02-6 is a valid CAS Registry Number.

Quinolone alkaloids from Evodia rutaecarpa
Tang, Yuan-Qing,Feng, Xiao-Zhang,Huang, Liang
, p. 719 - 722 (2007/10/03)
Five new quinolone alkaloids were isolated from the fruits of Evodia rutaecarpa, together with seven known ones. Their structures were determined on the basis of spectral data and chemical reactions.
The Chemistry of 2H-3,1-Benzoxazine-2,4(1H)-dione (Isatoic Anhydride). 17. Synthesis of 2-Alkyl-4-quinolone Alkaloids via a One-step Reaction of N-Methylisatoic Anhydride with Methyl Ketone Enolates
Coppola, Gary M.
, p. 491 - 494 (2007/10/02)
Lithium enolates derived from aliphatic methyl ketones react with N-methylisatoic anhydride (5) at -78 deg C to give 2-alkyl-4-quinolone alkaloids 7 in a single step.The method was used to synthesize both double bond isomers of 1-methyl-2-(8-tridecenyl)-4(1H)-quinolinone (8) thereby showing that the alkaloid evocarpine possesses the Z-olefin stereochemistry 8a.Reduction of 8a provided the alkaloid dihydroevocarpine (16).Compound 16 was also directly prepared from the reaction of 5 with the lithium enolate of 2-pentadecanone.
