112181-39-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 112181-39-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,1,8 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 112181-39:
(8*1)+(7*1)+(6*2)+(5*1)+(4*8)+(3*1)+(2*3)+(1*9)=82
82 % 10 = 2
So 112181-39-2 is a valid CAS Registry Number.

A Novel One Step Synthesis of Pyrazolopyridine Derivatives
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
