42198-68-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 42198-68-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,1,9 and 8 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 42198-68:
(7*4)+(6*2)+(5*1)+(4*9)+(3*8)+(2*6)+(1*8)=125
125 % 10 = 5
So 42198-68-5 is a valid CAS Registry Number.

Mechanism leading to the observed product of intramolecular aryl Diels-Alder reaction

Chackalamannil, Samuel,Doller, Darío,Eagen, Keith

, p. 5101 - 5103 (2007/10/03)

A mechanistic investigation into the recently reported intramolecular aryl Diels-Alder reaction was carried out using deuterium labeling. These studies led to the conclusion that the initial Diels-Alder adduct is isomerized to a highly conjugated tetra-ene intermediate which undergoes a stereospecific suprafacial 1,5-dienyl hydrogen shift to give the observed product.
