(E)-2-methoxy-3-(phenylsulfonyl)propene is an organic chemical compound characterized by a double bond between the second and third carbon atoms (E configuration), a methoxy group (-OCH3) attached to the second carbon, and a phenylsulfonyl group (-SO2Ph) attached to the third carbon. This molecule is a derivative of allene, with a phenylsulfonyl group replacing one of the terminal hydrogens. It is a colorless liquid with a molecular weight of 214.25 g/mol and a melting point of -40°C. The compound is used as an intermediate in the synthesis of various pharmaceuticals and agrochemicals, and it exhibits unique reactivity due to the presence of the electron-withdrawing sulfonyl group and the electron-donating methoxy group.

Check Digit Verification of cas no

The CAS Registry Mumber 2525-45-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,2 and 5 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2525-45:
(6*2)+(5*5)+(4*2)+(3*5)+(2*4)+(1*5)=73
73 % 10 = 3
So 2525-45-3 is a valid CAS Registry Number.
