Used in Natural Product Extraction:
Methylene, dichlorois used as an extraction solvent for caffeine and other natural products, allowing for the efficient separation and purification of these compounds from their sources.
However, it is important to note that Methylene, dichlorois considered to be moderately toxic and a potential carcinogen. Long-term exposure can pose health risks to the central nervous system, liver, and lungs. Additionally, it has been linked to environmental concerns, such as groundwater contamination and its contribution to greenhouse gas emissions. Due to these health and environmental concerns, the chemical has been subject to regulatory restrictions in some countries.
Check Digit Verification of cas no
The CAS Registry Mumber 1605-72-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,0 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1605-72:
(6*1)+(5*6)+(4*0)+(3*5)+(2*7)+(1*2)=67
67 % 10 = 7
So 1605-72-7 is a valid CAS Registry Number.

Vaccum ultraviolet absorption spectra and photodissociative excitation of CHBr2Cl and CHBrCl2
Ibuki, Toshio,Hiraya, Atsunari,Shobatake, Kosuke
, p. 8793 - 8798 (1992)
Photoabsorption and fluorescence excitation spectra of CHBr2Cl and CHBrCl2 trihalomethanes were measured in the 106-200 nm region using synchrotron radiation as a light source.Main photoabsorption bands observed are assigned as the Rydberg transitions of the outer shell orbitals.In the photoexcitation of CHBr2Cl a diffuse emission band of CHCl(1A''--> 1A') was observed in the 500-800 nm region.The radiative lifetime of the CHCl(1A'') state was first determined to be 7.01+/-0.25 μs.In the photolysis of CHBrCl2 at 121.6 nm, the formation of CHCl(1A'') and CCl2(1B1)radicals were observed.The fluorescence thresholds for CHBr2Cl and CHBrCl2 start at 162 and 159 nm with the maximum yields of 5percent and 11percent at 122 and 119 nm, respectively.
