Check Digit Verification of cas no

The CAS Registry Mumber 80810-53-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,8,1 and 0 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 80810-53:
(7*8)+(6*0)+(5*8)+(4*1)+(3*0)+(2*5)+(1*3)=113
113 % 10 = 3
So 80810-53-3 is a valid CAS Registry Number.

The Thermal ortho-Substitution of Phenols by Vinyl Ethers

Pinhey, John T.,Xuan, Phan Thanh

, p. 69 - 80 (2007/10/02)

Pyrolysis of a mixture of phenol and 3,4-dihydro-2H-pyran (6) at 150-180 deg C resulted in the formation of 2-(tetrahydro-2H-pyran-2-yl)phenol (3a) in moderate yield.This selective ortho-substitution reaction has been investigated for a range of phenols and a number of vinyl ethers.While it was found to be a fairly general reaction for phenols, only with the vinyl ether (6) and 2,3-dihydrofuran (28a) was the reaction found to be regioselective.Aluminium phenylate strongly catalyses the reaction of phenol with (6), which proceeded under these conditions at room temperature.An ene-type mechanism is proposed for the reaction.
