577741-90-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 577741-90-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,7,7,7,4 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 577741-90:
(8*5)+(7*7)+(6*7)+(5*7)+(4*4)+(3*1)+(2*9)+(1*0)=203
203 % 10 = 3
So 577741-90-3 is a valid CAS Registry Number.

Mechanisms for the Uncatalyzed and Hydrogen Ion Catalyzed Reactions of a Simple Quinone Methide with Solvent and Halide Ions
Richard, John P.
, p. 4588 - 4595 (2007/10/02)
The quinone methide 4-[bis(trifluoromethyl)methylene]cyclohexa-2,5-dienone (1) has been prepared in situ from the solvolysis of 4-MeOArC(CF3)2OTs in 50:50 (v/v) trifluoroethanol/water, and its reactions with solvent and halide ions h
