1552-71-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1552-71-2 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 1 respectively.
Calculate Digit Verification of CAS Registry Number 1552-71:
(6*1)+(5*5)+(4*5)+(3*2)+(2*7)+(1*1)=72
72 % 10 = 2
So 1552-71-2 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.
