Check Digit Verification of cas no

The CAS Registry Mumber 91029-25-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,0,2 and 9 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 91029-25:
(7*9)+(6*1)+(5*0)+(4*2)+(3*9)+(2*2)+(1*5)=113
113 % 10 = 3
So 91029-25-3 is a valid CAS Registry Number.

CONDENSATION OF AZOMETHINES WITH DIMETHYL ACETYLENEDICARBOXYLATE

Prostakov, N. S.,Gaivoronskaya, L. A.,Zakharov, V. F.,Kuznetsov, V. V.,Das, S. K.,Aliev, A. E.

, p. 295 - 300 (1984)

The condensation of dimethyl acetylenedicarboxylate with benzylidene- and cyclohexylideneaniline, as well as with cyclohexylidene-p-toluidine and cyclohexylidene-p-anisidine, under various conditions gave 1:1, 1:2, and 1:3 adducts.The structures of the isolated substances, which are formed as a result of the addition of the ester to the azomethines with subsequent 1,5-prototropic rearrangement (arylcyclohexenylvinylamines), as well as by cycloaddition (substituted dihydropyridines and spiro-cyclohexanedihydropyridines), are discussed.
