Check Digit Verification of cas no

The CAS Registry Mumber 15620-71-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,6,2 and 0 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 15620-71:
(7*1)+(6*5)+(5*6)+(4*2)+(3*0)+(2*7)+(1*1)=90
90 % 10 = 0
So 15620-71-0 is a valid CAS Registry Number.

Selective reduction of nitroaromatic compounds on silver nanoparticles by visible light

, p. 1024 - 1028 (2012/10/29)

For the first time, we report experimentally and theoretically that nitroaromatic compounds, 2,4-dinitrobenzenethiol and 4-chloro-2- nitrobenzenethiol, on silver sols can be selectively reduced to 2-amino-4-nitrobenzenethiol and 2-amino-4-chlorobenzenethiol simply by irradiating with a visible light in ambient conditions, and the selective photoreduction is a very facile process. The results of quantum chemical calculations are in good agreement with our experimental data. Copyright
