Check Digit Verification of cas no
The CAS Registry Mumber 2894-87-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,9 and 4 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2894-87:
(6*2)+(5*8)+(4*9)+(3*4)+(2*8)+(1*7)=123
123 % 10 = 3
So 2894-87-3 is a valid CAS Registry Number.

Pyrolysis reactions of nonafluorobiphenyl-4-yl prop-2-enyl ether: A remarkable rearrangement reaction of an intramolecular Diels-Alder product

The pyrolysis reaction of nonafluorobiphenyl-4-yl prop-2-enyl ether were studied. The reaction was proposed as a remarkable rearrangement reaction of an intramolecular Diels-Alder product. The flash vapor pyrolysis of the compound performed at 350 °C gave a complex mixture containing the products obtained from Diels-Alder reactions. The molecular structure of the compounds obtained was characterized by x ray crystallography.
