Check Digit Verification of cas no
The CAS Registry Mumber 117539-59-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,5,3 and 9 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 117539-59:
(8*1)+(7*1)+(6*7)+(5*5)+(4*3)+(3*9)+(2*5)+(1*9)=140
140 % 10 = 0
So 117539-59-0 is a valid CAS Registry Number.

SYNTHESIS AND POLYMERIZATION OF SOME ETHYNYL TRIFLUOROMETHYL NAPHTHALENES

Some bromonaphthoic acids were fluorinated with SF4 to bromo(trifluoromethyl)naphthalenes.Although a reaction of Grignard reagent of one of the bromides with Cl2C=CF2 gave low yield of a (dichlorofluorovinyl)(trifluoromethyl)naphthalene, lithio derivatives gave the desired ethynyl(trifluoromethyl)naphthalenes in improved yields after subsequent eliminations of the vinylic halogens with n-butyllithium.Polymerization of the acetylenes was carried out with photo-activated W(CO)6 catalyst to yield high-molecular-weight polymers.
