1174400-52-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1174400-52-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,4,4,0 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1174400-52:
(9*1)+(8*1)+(7*7)+(6*4)+(5*4)+(4*0)+(3*0)+(2*5)+(1*2)=122
122 % 10 = 2
So 1174400-52-2 is a valid CAS Registry Number.

A Lewis acid promoted oxidative cyclization
Donohoe, Timothy J.,Winship, Paul C. M.,Walter, Daryl S.
experimental part, p. 6394 - 6397 (2009/12/06)
(Chemical Equation Presented) Replacing trifluoroacetic acid with a catalytic amount of Lewis acid in the osmium mediated oxidative cyclization results in higher yielding reactions that can proceed nearly an order of magnitude faster. The osmium loading c
