Check Digit Verification of cas no

The CAS Registry Mumber 33739-60-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,7,3 and 9 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 33739-60:
(7*3)+(6*3)+(5*7)+(4*3)+(3*9)+(2*6)+(1*0)=125
125 % 10 = 5
So 33739-60-5 is a valid CAS Registry Number.

Synthesis and Reactions of 3-Carboxytropolone. Conversion to Heterocycle-fused Troponoid Compounds

Zhang, Luo-Cheng,Imafuku, Kimiaki

, p. 717 - 720 (2007/10/02)

The haloform reaction of 3-acetyltropolone (1) afforded 3-carboxytropolone (2) which was treated with diazomethane to give 2-methoxy-3-methoycarbonyltropone (3a) and 2-methoxy-7-methoxycarbonyltropone (3b).The tropolone 2 reacted with hydrazine to afford

VINYLIC SUBSTITUTION ON TROPONOID CATALYZED BY PALLADIUM COMPLEXES, AND FORMATION OF NEW C-Pd ?-COMPLEXES OF TROPONOID

Horino, Hiroshi,Inoue, Naoto,Asao, Toyonobu

, p. 741 - 744 (2007/10/02)

The reaction of 3-, 4- and 5-halotropolones with olefins catalyzed by palladium(0) complex gave 3-, 4- and 5-(substituated vinyl)tropolones respectively.Similarly, 2-chlorotropone gave 2-styryltropones.Some tropolonyl- and troponylpalladium-?-complexes we
