161458-29-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 161458-29-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,4,5 and 8 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 161458-29:
(8*1)+(7*6)+(6*1)+(5*4)+(4*5)+(3*8)+(2*2)+(1*9)=133
133 % 10 = 3
So 161458-29-3 is a valid CAS Registry Number.

A method for the synthesis of the enantiomers of propafenone
Ecker,Fleischhacker,Noe
, p. 691 - 695 (1994)
The enantiomers of the antiarrhythmic drug propafenone were synthesized using a recoverable acetal protective group. The key-step in the synthesis was the protection of the cyanohydrin 7 with enantiomerically pure MBF-lactol, which allows not only easy se
