128883-51-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128883-51-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,8,8 and 3 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 128883-51:
(8*1)+(7*2)+(6*8)+(5*8)+(4*8)+(3*3)+(2*5)+(1*1)=162
162 % 10 = 2
So 128883-51-2 is a valid CAS Registry Number.

A Simple Synthesis of Novel 2-Pyridones from Chalcones
Al-Arab, Mohammad M.
, p. 523 - 525 (2007/10/02)
Several novel 2-pyridones were synthesized in good yields from a simple one-pot reaction by the condensation of different substituted chalcones and malonamide using ethoxide in ethanol at room temperature.The structures of these 2-pyridones were elucidate
