65714-80-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 65714-80-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,7,1 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 65714-80:
(7*6)+(6*5)+(5*7)+(4*1)+(3*4)+(2*8)+(1*0)=139
139 % 10 = 9
So 65714-80-9 is a valid CAS Registry Number.

The conversion of 7-acetoxyroyleanone to 14-methoxytaxodione
Faucher, Anne-Marie,Burnell, Robert H.
, p. 1 - 4 (2007/10/02)
7-Acetoxyroyleanone (1a) has been converted in five steps to the methoxy-p-quinone 9.Since the latter was the penultimate intermediate in Eugster's partial synthesis of 14-methoxytaxodione (2), the transformation reported represents a formal synthesis of the latter.Key words: 7-acetoxyroyleanone, 14-methoxytaxodione, synthesis.
