82247-51-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82247-51-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,2,4 and 7 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 82247-51:
(7*8)+(6*2)+(5*2)+(4*4)+(3*7)+(2*5)+(1*1)=126
126 % 10 = 6
So 82247-51-6 is a valid CAS Registry Number.

An Efficient Total Synthesis of (+/-)-Aklavinone
Boeckman, Robert K.,Sum, F.-W.
, p. 4604 - 4610 (1982)
An 11-step total synthesis of (+/-)-aklavinone from 1,3-cyclohexadione is reported.The key steps include a Diels-Alder condensation of 3 and 4 and the stereoselective aldol condensation of 21 to 22.The overall yield is ca. 13percent.
