189766-47-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 189766-47-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,7,6 and 6 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 189766-47:
(8*1)+(7*8)+(6*9)+(5*7)+(4*6)+(3*6)+(2*4)+(1*7)=210
210 % 10 = 0
So 189766-47-0 is a valid CAS Registry Number.

Improved Synthesis of the Enantiomers of Propafenone Using Chiral Building Blocks
Ecker,Noe,Fleischhacker
, p. 53 - 59 (2007/10/03)
A short and efficient synthesis of the enantiomers of the antiarrhythmic drug propafenone (1) is described using both (R)-isopropylideneglycerol tosylate and (S)-glycidyl tosylate as chiral building blocks. The key step of the high yield synthesis is the
