Check Digit Verification of cas no

The CAS Registry Mumber 110699-61-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,6,9 and 9 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 110699-61:
(8*1)+(7*1)+(6*0)+(5*6)+(4*9)+(3*9)+(2*6)+(1*1)=121
121 % 10 = 1
So 110699-61-1 is a valid CAS Registry Number.

Cycloadditions, 12. - Influence of Aromatic Alkyl Groups on the Intramolecular Diels-Alder Reaction of Aryl Allenecarboxylates and of Allenecarboxanilides

Himbert, Gerhard,Fink, Dieter,Diehl, Klaus

, p. 431 - 442 (2007/10/02)

The aryl allenecarboxylates 4a-o and the allenecarboxanilides 9a, b, e, h, and l, which differ from one another only by the number or by the size of the alkyl groups attached to the arene, are synthesized by the ylide method via the appropriately substituted 2-halo-, 2-phosphonio-, and 2-phosphoranylideneacetic acid derivatives (1-->2-->3-->4 and 6-->7-->8-->9, resp.).By refluxing in xylene they are transformed into the tricyclic compounds 5 and 10; the rates and their differences are discussed.
