Check Digit Verification of cas no

The CAS Registry Mumber 181027-20-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,0,2 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 181027-20:
(8*1)+(7*8)+(6*1)+(5*0)+(4*2)+(3*7)+(2*2)+(1*0)=103
103 % 10 = 3
So 181027-20-3 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
