Check Digit Verification of cas no

The CAS Registry Mumber 147196-13-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,1,9 and 6 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 147196-13:
(8*1)+(7*4)+(6*7)+(5*1)+(4*9)+(3*6)+(2*1)+(1*3)=142
142 % 10 = 2
So 147196-13-2 is a valid CAS Registry Number.

1,3-Dipolar Cycloaddition Reactions of 2,4,6-Cycloheptatrien-1-imines with Benzonitrile Oxides Leading to 1,2,4-Oxadiazaspiroundeca-2,6,8,10-tetraenes

Ito, Kazuaki,Saito, Katsuhiro

, p. 3539 - 3548 (1995)

1,3-Dipolar cycloaddition reactions of N-aryl-2,4,6-cycloheptatrien-1-imines with p-substituted benzonitrile oxides afforded -type cycloadducts in considerable yields.A study of the substituent effect on the reaction rate revealed that the reactions proceeded through nucleophilic reactions of imines to nitrile oxides.Thermal isomerizations and addition reactions of the adducts showed that the contribution of a valence isomerization between cycloheptatriene and norcaradiene lay to the side of the cycloheptatriene form.A comparison of the UV spectra between the adduct and its derivative, which was reduced by catalytic hydrogenation, implies that the spiroconjugation between cycloheptatriene and a five-membered heterocyclic moiety causes a shift of the equilibrium.
