Phosphorane, tetrachloro(2-phenylethenyl)-, also known as tetrachlorophosphonium 2-phenylethenide, is a phosphorus-containing organometallic compound with the chemical formula C8H6Cl4P. It is a colorless, crystalline solid that is highly sensitive to moisture and air. Phosphorane, tetrachloro(2-phenylethenyl)- is formed by the reaction of 2-phenylethenyl chloride with tetrachlorophosphorane, resulting in the formation of a phosphonium salt. It is used as an intermediate in the synthesis of various organophosphorus compounds, such as phosphine oxides, phosphine sulfides, and phosphonates. Due to its reactivity, it is essential to handle Phosphorane, tetrachloro(2-phenylethenyl)- with care, using appropriate safety measures and under controlled conditions.

Check Digit Verification of cas no

The CAS Registry Mumber 4895-49-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,9 and 5 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4895-49:
(6*4)+(5*8)+(4*9)+(3*5)+(2*4)+(1*9)=132
132 % 10 = 2
So 4895-49-2 is a valid CAS Registry Number.
