65567-99-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 65567-99-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,5,6 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 65567-99:
(7*6)+(6*5)+(5*5)+(4*6)+(3*7)+(2*9)+(1*9)=169
169 % 10 = 9
So 65567-99-9 is a valid CAS Registry Number.

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
