But-2-enylsulfanyl cyanate, also known as 2-butenylsulfanyl cyanate or 2-butenylsulfanyl isocyanate, is an organic compound with the chemical formula C5H7NS. It is a colorless liquid that is soluble in organic solvents and has a pungent odor. but-2-enylsulfanyl cyanate is characterized by the presence of a but-2-enyl group (a four-carbon chain with a double bond between the second and third carbons) and a sulfanyl group (a sulfur atom bonded to a hydrogen atom) attached to a cyanate group (a carbon atom triple-bonded to a nitrogen atom). But-2-enylsulfanyl cyanate is primarily used as an intermediate in the synthesis of various chemicals, including pharmaceuticals, agrochemicals, and other specialty chemicals. Due to its reactivity, it is important to handle but-2-enylsulfanyl cyanate with care, as it can be toxic and may cause irritation to the skin, eyes, and respiratory system.
The CAS Registry Mumber 2253-92-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,5 and 3 respectively; the second part has 2 digits, 9 and 2 respectively. Calculate Digit Verification of CAS Registry Number 2253-92: (6*2)+(5*2)+(4*5)+(3*3)+(2*9)+(1*2)=71 71 % 10 = 1 So 2253-92-1 is a valid CAS Registry Number.
