Check Digit Verification of cas no
The CAS Registry Mumber 143878-20-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,8,7 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 143878-20:
(8*1)+(7*4)+(6*3)+(5*8)+(4*7)+(3*8)+(2*2)+(1*0)=150
150 % 10 = 0
So 143878-20-0 is a valid CAS Registry Number.

The enantioselective synthesis of (S)-(+)-mianserin and (S)-(+)-epinastine
Roszkowski, Piotr,Maurin,Czarnocki, Zbigniew
, p. 1509 - 1513 (2015)
A simple enantioselective synthetic procedure for the preparation of mianserin and epinastine in optically pure form is described. The key step in the synthetic pathway is the asymmetric reduction of the cyclic imine using asymmetric transfer hydrogenation conditions.
