Check Digit Verification of cas no

The CAS Registry Mumber 81096-10-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,0,9 and 6 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 81096-10:
(7*8)+(6*1)+(5*0)+(4*9)+(3*6)+(2*1)+(1*0)=118
118 % 10 = 8
So 81096-10-8 is a valid CAS Registry Number.

Stereocontrol in the Intramolecular Diels-Alder Reaction. 4. A Remarkable Effect of Overlap Requirements in the Connecting Chain

Boeckman, Robert K.,Demko, Donald M.

, p. 1789 - 1792 (2007/10/02)

The intramolecular Diels-Alder cyclizations of two triene diesters derived from (E)-3,5-hexadienoic acid have been investigated.The cyclizations proceed remarkably sluggishly and only after double-bond isomerization to the sorbate derivative has occurred.The reasons behind this unusual behavior were investigated, and evidence points strongly to the effects of overlap requirements of the ester linkage in the transition state as the major factor.
