Check Digit Verification of cas no
The CAS Registry Mumber 73505-32-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,5,0 and 5 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 73505-32:
(7*7)+(6*3)+(5*5)+(4*0)+(3*5)+(2*3)+(1*2)=115
115 % 10 = 5
So 73505-32-5 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.
