91491-61-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 91491-61-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,4,9 and 1 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 91491-61:
(7*9)+(6*1)+(5*4)+(4*9)+(3*1)+(2*6)+(1*1)=141
141 % 10 = 1
So 91491-61-1 is a valid CAS Registry Number.

A study on the antioxidant activity of pyridylselenium compounds and their slow release from poly(acrylamide) hydrogels

Dhau, Jaspreet S.,Singh, Avtar,Singh, Amritpal,Sooch, Balwinder S.

, p. 687 - 699 (2014/06/09)

The antioxidant activity of pyridylselenium compounds has been evaluated by 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical and nitric oxide (NO) scavenging methods. Pyridylselenium compounds have shown far superior (100-1000 times) antioxidant property than ebselen. The control release of bis(2-pyridyl) diselenide from poly(acrylamide) hydrogels has been studied in order to evaluate its release mechanism and diffusion coefficient. The later study also demonstrates that the pyridylselenium loading into the polymer matrix increases the magnitude and the rate of the radical scavenging activity of the poly(acrylamide) hydrogels.
