30843-11-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 30843-11-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,8,4 and 3 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 30843-11:
(7*3)+(6*0)+(5*8)+(4*4)+(3*3)+(2*1)+(1*1)=89
89 % 10 = 9
So 30843-11-9 is a valid CAS Registry Number.

Phadke, R. C.,Rangnekar, D. W.
, p. 484 - 485 (2007/10/02)
A novel one step synthesis of pyrazolopyridines has been developed by condensation of N-amino-3-cyano-4,6-dimethyl-2(1H)-pyridone (1) with compounds containing acetyl or active methylene group in presence of anhydrous zinc chloride in refluxing dim
