19423-05-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 19423-05-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,4,2 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 19423-05:
(7*1)+(6*9)+(5*4)+(4*2)+(3*3)+(2*0)+(1*5)=103
103 % 10 = 3
So 19423-05-3 is a valid CAS Registry Number.

Synthesis and pharmacological study of aryloxypropanolamines substituted on carbon 2
Galons,Combet Farnoux,Miocque,et al.
, p. 23 - 27 (2007/10/02)
In a series of aryloxypropanolamines, substitution on carbon 2 by alkyl, aryl or aralkyl groups lowers the β-blocking activity. This effect increases with the size of the substituent.
