Check Digit Verification of cas no

The CAS Registry Mumber 190837-21-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,0,8,3 and 7 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 190837-21:
(8*1)+(7*9)+(6*0)+(5*8)+(4*3)+(3*7)+(2*2)+(1*1)=149
149 % 10 = 9
So 190837-21-9 is a valid CAS Registry Number.

A rearranged hydroperoxide from the reduction of artemisinin

Sy, Lai-King,Hui, Shi-Man,Cheung, Kung-Kai,Brown, Geoffrey D.

, p. 7493 - 7500 (1997)

Lithium aluminium hydride reduction of artemisinin produces two unexpected rearrangement products in addition to those reported previously. The structure of the major rearrangement product, a tertiary hydroperoxide, was determined by 2D-NMR and chemical reactions. A mechanism is proposed for this rearrangement, based on the observation that dihydroartemisinin can also be converted into the same hydroperoxide in alkaline solution.
