Check Digit Verification of cas no

The CAS Registry Mumber 83749-68-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,7,4 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 83749-68:
(7*8)+(6*3)+(5*7)+(4*4)+(3*9)+(2*6)+(1*8)=172
172 % 10 = 2
So 83749-68-2 is a valid CAS Registry Number.

SYNTHESIS OF 5H-PYRIDAZOINDOLES BY CONDENSATION OF 2-ACYLINDOLE-3-CARBOXYLIC ACIDS WITH HYDRAZINE

Zhungietu, G. I.,Zorin, L. M.,Gorgos, V. I.,Rekhter, M. A.

, p. 811 - 813 (2007/10/02)

5H-Pyridazoindol-1-ones were obtained by heating 2-acetylindole-3- or 2-aroylindole-3-carboxylic acids with hydrazine hydrate in ethylene glycol or alcohol. 1-Chloro-5H-pyridazoindoles are formed by treatment of 5H-pyridazoindol-1-one
