Dimethyldichloroselenurane, also known as DMDCS, is an organoselenium compound with the chemical formula (CH3)2SeCl2. It is a colorless, volatile liquid that is soluble in organic solvents. DMDCS is primarily used as a reagent in organic synthesis, particularly for the introduction of the selenocyanate group into organic molecules. It is synthesized by the reaction of selenium dioxide with dimethylamine and chlorine. Due to its reactivity, DMDCS is often used in the preparation of various organoselenium compounds, which have applications in pharmaceuticals, agrochemicals, and materials science. The compound should be handled with care, as it is toxic and can release toxic fumes when heated or exposed to moisture.

Check Digit Verification of cas no

The CAS Registry Mumber 1454-94-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,5 and 4 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1454-94:
(6*1)+(5*4)+(4*5)+(3*4)+(2*9)+(1*4)=80
80 % 10 = 0
So 1454-94-0 is a valid CAS Registry Number.

Reaction of selenonium ylides with activated acetylenes

Magdesieva, N. N.,Kyandzhetsian, R. A.,Gordeev, M. F.

, p. 2219 - 2227 (2007/10/02)

The reaction of dimethylaroylmethylselenonium bromides with dibenzoylacetylene in the presence of bases leads to the formation of a mixture of 2-aryl-3,5-diaroyl- and 2-aryl-4,5-diaroylfurans.The latter are easily converted into 2,4,7-triarylfuropy
