Check Digit Verification of cas no
The CAS Registry Mumber 5216-22-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,1 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 5216-22:
(6*5)+(5*2)+(4*1)+(3*6)+(2*2)+(1*2)=68
68 % 10 = 8
So 5216-22-8 is a valid CAS Registry Number.

A study was carried out on the reaction of perfluorinated toluene, m-xylene, p-xylene, mesitylene, and m-(1-propenyl)toluene with inorganic oxides in the presence of antimony pentafluoride.Depending on the reaction conditions, polyfluorinated acids resulting from the consecutive conversion of trifluoromethyl groups into carboxylic acid groups are obtained after hydrolysis of the reaction mixtures.
