Check Digit Verification of cas no
The CAS Registry Mumber 98083-43-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,0,8 and 3 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 98083-43:
(7*9)+(6*8)+(5*0)+(4*8)+(3*3)+(2*4)+(1*3)=163
163 % 10 = 3
So 98083-43-3 is a valid CAS Registry Number.

Ruechardt, Christoph,Hassmann, Volker
, p. 908 - 927 (2007/10/02)
Procedures are described for a one-pot synthesis of 1H-indazole and substituted indazoles 3 in good yield (Table 1) from o-toluidines 2, alkyl nitrite or nitrous oxides, potassium acetate, and acetic anhydride in benzene.The spectroscopic properties of substituted indazoles (Tables 2-4) are discussed. - 4-Phenylcinnoline (18) is prepared by the same procedure from o-(α-methylenebenzyl)aniline.
