(Z)-2-chloro-3-(p-tolyl)acrylic acid is a chemical compound with the molecular formula C10H9ClO2. It is a derivative of acrylic acid, featuring a chlorine atom at the 2nd carbon and a p-tolyl group (a methyl group attached to a phenyl ring) at the 3rd carbon. This organic compound is characterized by its conjugated double bond system, which gives it unique chemical properties and reactivity. It is used in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals due to its ability to form stable intermediates and react with a wide range of reagents. The (Z)-configuration indicates the geometric arrangement of the double bond, with the chlorine and p-tolyl groups on the same side of the molecule.

Check Digit Verification of cas no

The CAS Registry Mumber 1552-73-4 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 3 respectively.
Calculate Digit Verification of CAS Registry Number 1552-73:
(6*1)+(5*5)+(4*5)+(3*2)+(2*7)+(1*3)=74
74 % 10 = 4
So 1552-73-4 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.
