847186-64-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 847186-64-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,7,1,8 and 6 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 847186-64:
(8*8)+(7*4)+(6*7)+(5*1)+(4*8)+(3*6)+(2*6)+(1*4)=205
205 % 10 = 5
So 847186-64-5 is a valid CAS Registry Number.

Regiospecific topochemical reactions controlled by trifluoromethyl directing groups

A parallel, offset-stacked orientation was found in the crystal packing of E,E-1,4-di(o-trifluoromethyl)phenyl-1,3-butadiene. UV-irradiation of the powered crystalline sample resulted in a quantitative conversion to a single [2 + 2] cycloaddition product.
