Check Digit Verification of cas no
The CAS Registry Mumber 153977-22-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,9,7 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 153977-22:
(8*1)+(7*5)+(6*3)+(5*9)+(4*7)+(3*7)+(2*2)+(1*2)=161
161 % 10 = 1
So 153977-22-1 is a valid CAS Registry Number.

Synthesis of atovaquone
Williams, David R.,Clark, Michael P.
, p. 7629 - 7632 (1998)
A short synthesis of atovaquone I is achieved via the radical coupling of the trans-1,4-substituted cyclohexyl mono-oxalate 2 and 2- chloronapthoquinone under phase transfer conditions.
