159622-29-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 159622-29-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,6,2 and 2 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 159622-29:
(8*1)+(7*5)+(6*9)+(5*6)+(4*2)+(3*2)+(2*2)+(1*9)=154
154 % 10 = 4
So 159622-29-4 is a valid CAS Registry Number.

Chemoenzymatic route to β-blockers via 3-hydroxy esters
Wuensche, Kerstin,Schwaneberg, Ulrich,Bornscheuer, Uwe T.,Meyer, Hartmut H.
, p. 2017 - 2022 (2007/10/03)
Enantiomerically pure precursors of β-blockers (propranolol, alprenolol and 1-(isopropylamino)-3-p-methoxy-phenoxy-2-propanol) were synthesized. Key step is the lipase-catalyzed kinetic resolution of rac-3-hydroxy esters either by O-acylation using vinyl
