Check Digit Verification of cas no

The CAS Registry Mumber 312493-45-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,2,4,9 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 312493-45:
(8*3)+(7*1)+(6*2)+(5*4)+(4*9)+(3*3)+(2*4)+(1*5)=121
121 % 10 = 1
So 312493-45-1 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

Alternative reagents for the tritylation of alcohols

Jyothi,Mahalingam,Ilangovan,Sharma

, p. 2091 - 2101 (2008/02/04)

Two new tritylation reagents [viz. p-methoxybenzyl trityl ether (p-MBTE) and prenyl trityl ether (PTE)] were prepared. These two new reagents were utilized efficiently for the tritylation of alcohols, using DDQ or 20 mol% DDQ-3 eq. Mn(OAc)3. Copyright Tay
