(Z)-2-chloro-3-(4-methoxyphenyl)acrylic acid is a chemical compound with the molecular formula C9H7ClO3. It is an organic molecule that belongs to the class of acrylic acids, characterized by the presence of a double bond between the carbon atoms. The compound features a chloro group at the 2nd carbon position and a 4-methoxyphenyl group attached to the 3rd carbon position. The 4-methoxyphenyl group consists of a benzene ring with a methoxy group (-OCH3) at the 4th position. This molecule is known for its potential applications in the synthesis of pharmaceuticals and other organic compounds due to its unique structure and reactivity. It is important to note that the (Z) configuration indicates the geometric arrangement of the double bond, with the chlorine and methoxyphenyl groups on the same side of the double bond.

Check Digit Verification of cas no

The CAS Registry Mumber 1552-72-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,5 and 2 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1552-72:
(6*1)+(5*5)+(4*5)+(3*2)+(2*7)+(1*2)=73
73 % 10 = 3
So 1552-72-3 is a valid CAS Registry Number.

supporting information; experimental part, p. 5352 - 5354 (2012/06/30)

Finely-tuned ruthenium-catalyzed highly chemoselective and enantioselective hydrogenation of γ-halo-γ,δ-unsaturated-β-keto esters at the carbonyl group was achieved under neutral reaction conditions (ee up to 97%). Both olefin and alkenyl halogen moieties, which are labile under hydrogenation conditions, remained untouched during the reaction.
