1172581-65-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1172581-65-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,2,5,8 and 1 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1172581-65:
(9*1)+(8*1)+(7*7)+(6*2)+(5*5)+(4*8)+(3*1)+(2*6)+(1*5)=155
155 % 10 = 5
So 1172581-65-5 is a valid CAS Registry Number.

ZnO nanoparticles-catalyzed cyclocondensation reaction of arylmethylidenepyruvic acids with 6-aminouracils
Abdolmohammadi, Shahrzad
, p. 32 - 36 (2013/08/24)
A new, efficient, and solvent-free cyclocondensation reaction of arylmethylidenepyruvic acids with 6- aminouracils is presented that uses a catalytic amount of ZnO nanoparticles (ZnO Nps) as a recyclable catalyst at 70 °C. This protocol has the advantages
