Check Digit Verification of cas no
The CAS Registry Mumber 87322-20-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,3,2 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 87322-20:
(7*8)+(6*7)+(5*3)+(4*2)+(3*2)+(2*2)+(1*0)=131
131 % 10 = 1
So 87322-20-1 is a valid CAS Registry Number.

Stereoselective total synthesis of (+)-artemisinin
Yadav,Satheesh Babu,Sabitha
, p. 387 - 389 (2007/10/03)
The total synthesis of the novel antimalarial drug, a sesquiterpene endoperoxide, (+)-artemisinin is described. The approach is flexible and stereoselective. The use of an intermolecular radical reaction on an intermediate iodolactone and a Wittig reaction on a ketone were employed for the synthesis.
