Check Digit Verification of cas no

The CAS Registry Mumber 143746-69-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,7,4 and 6 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 143746-69:
(8*1)+(7*4)+(6*3)+(5*7)+(4*4)+(3*6)+(2*6)+(1*9)=144
144 % 10 = 4
So 143746-69-4 is a valid CAS Registry Number.

Microwave Assisted Synthesis of Heterocyclic Fused Quinones in Dry Media

Acosta, A.,Cruz, P. de la,Miguel, P. De,Diez-Barra, E.,Hoz, A. de la,et al.

, p. 2165 - 2168 (1995)

Microwave assisted cyclization of several 2-thenoylbenzoic acids 2 catalysed with clays in dry media is studied.Some clays were tested and Montmorillonite K-10, free of quarz and feldspar, was shown to be an effective catalyst for their easy conversion into the corresponding heterocyclic fused quinone in good yields.A specific effect of microwave irradiation accelerating the reaction with respect to conventional heating in the same conditions is observed.
