Check Digit Verification of cas no
The CAS Registry Mumber 22032-48-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,0,3 and 2 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 22032-48:
(7*2)+(6*2)+(5*0)+(4*3)+(3*2)+(2*4)+(1*8)=60
60 % 10 = 0
So 22032-48-0 is a valid CAS Registry Number.

The Synthesis of Cholesteryl Alkyl Ethers
Halperin, G.,Gatt, S.
, p. 39 - 42 (2007/10/02)
Seventeen cholesteryl alkyl ethers were synthesized through alcoholysis of cholesterol p-toluenesulfonate.This method was found superior to the etherification of sodium or potassium cholesterylate with alkyl halides or methanesulfonates, especially for the preparation of long-chain unsaturated alkyl ethers of cholesterol of high specific activity.
