2H-Pyran, tetrahydro-2-[(1-methyl-2-propenyl)oxy]-, also known as 2-isopropenyl-2-oxazoline, is a heterocyclic organic compound with the molecular formula C7H13NO. It is a colorless liquid with a density of 0.92 g/cm3 and a boiling point of 150-152°C. 2H-Pyran, tetrahydro-2-[(1-methyl-2-propenyl)oxy]- is characterized by a pyran ring, which is a six-membered oxygen-containing ring, and a tetrahydro structure, indicating that it has four hydrogen atoms attached to the ring. The 2-[(1-methyl-2-propenyl)oxy] group suggests the presence of an isopropenyl (allyl) ether side chain, which contributes to its reactivity and potential applications in organic synthesis. It is commonly used as a building block in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals due to its unique structure and reactivity.
The CAS Registry Mumber 72908-63-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,9,0 and 8 respectively; the second part has 2 digits, 6 and 3 respectively. Calculate Digit Verification of CAS Registry Number 72908-63: (7*7)+(6*2)+(5*9)+(4*0)+(3*8)+(2*6)+(1*3)=145 145 % 10 = 5 So 72908-63-5 is a valid CAS Registry Number.
