200573-72-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 200573-72-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,5,7 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 200573-72:
(8*2)+(7*0)+(6*0)+(5*5)+(4*7)+(3*3)+(2*7)+(1*2)=94
94 % 10 = 4
So 200573-72-4 is a valid CAS Registry Number.

Epimerization in acid degradation products of artemisinin
Hui, Shi-Man,Ngo, Koon-Sin,Brown, Geoffrey D.
, p. 3435 - 3442 (2007/10/03)
Treatment of artemisinin 1 with acid leads to either a cyclohexane dione degradation product 10, which is a useful intermediate for biosynthetic studies of artemisinin, or to a decalin system which has undergone epimerization 8. It is shown by NMR spectro
