Check Digit Verification of cas no

The CAS Registry Mumber 1180000-21-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,0,0,0 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1180000-21:
(9*1)+(8*1)+(7*8)+(6*0)+(5*0)+(4*0)+(3*0)+(2*2)+(1*1)=78
78 % 10 = 8
So 1180000-21-8 is a valid CAS Registry Number.

Remote-control photoswitching using NIR light

Carling, Carl-Johan,Boyer, John-Christopher,Branda, Neil R.

, p. 10838 - 10839 (2009)

(Chemical Equation Presented) Near-infrared (NIR) light is used to toggle photoswitches back and forth between their two isomers even though the chromophores do not significantly absorb this type of light. The reactions are achieved through a "remote control" process by using photon up-converting hexagonal NaYF4 nanocrystals doped with lanthanide ions. These nanoparticles absorb 980 nm light and convert it to wavelengths that can be used to trigger the photoswitches offering a practical means to potentially achieve 3D-data storage, drug-delivery, and photolithography.
