1198081-80-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1198081-80-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,8,0,8 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1198081-80:
(9*1)+(8*1)+(7*9)+(6*8)+(5*0)+(4*8)+(3*1)+(2*8)+(1*0)=179
179 % 10 = 9
So 1198081-80-9 is a valid CAS Registry Number.

FeCl3-catalyzed tritylation of alcohols in ionic liquids
Sreedhar,Radhika,Neelima,Chowdary,Rao, M. V. Basaveswara
experimental part, p. 3785 - 3795 (2009/12/08)
A simple and efficient protection of alcohols as trityl ethers is described using trityl chloride in the presence of 5mol% FeCl3 as catalyst in ionic liquids at room temperature in shorter reaction times. This mild and efficient method gives access to the
