Check Digit Verification of cas no

The CAS Registry Mumber 40178-31-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,1,7 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 40178-31:
(7*4)+(6*0)+(5*1)+(4*7)+(3*8)+(2*3)+(1*1)=92
92 % 10 = 2
So 40178-31-2 is a valid CAS Registry Number.

Synthesis of 5-(Substituted Styryl)-2-aminotropones

Imafuku, Kimiaki,Kobayashi, Toshio,Matsumura, Hisashi

, p. 181 - 184 (1985)

The methylation of 4-styryltropolones with diazomethane afforded 2-methoxy-4-styryltropones (2a-g) and 2-methoxy-6-styryltropones.The reactions of 2a-g with hydrazine gave 2-hydrazino derivatives, which were converted to 2-chloro derivatives 5a-g.Ammonoly
