Check Digit Verification of cas no

The CAS Registry Mumber 98294-45-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,2,9 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 98294-45:
(7*9)+(6*8)+(5*2)+(4*9)+(3*4)+(2*4)+(1*5)=182
182 % 10 = 2
So 98294-45-2 is a valid CAS Registry Number.

A STUDY OF THE INTRAMOLECULAR CYCLIZATION OF ESTERS OF 3-ARYLAZOINDOL-2-YLACETIC ACIDS

Trofimov, F. A.,Garnova, V. I.,Tsyshkova, N. G.

, p. 538 - 541 (1985)

A method is proposed for the synthesis of the new heterocyclic system pyridazinoindole which is based on the intramolecular condensation of ethyl 3-arylazoindol-2-ylacetates in the presence of bases.
