253779-05-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 253779-05-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,3,7,7 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 253779-05:
(8*2)+(7*5)+(6*3)+(5*7)+(4*7)+(3*9)+(2*0)+(1*5)=164
164 % 10 = 4
So 253779-05-4 is a valid CAS Registry Number.

A short stereoselective synthesis of a cyclopropyl analog of γ- aminobutyric acid (GABA)
Mohapatra, Debendra K.
, p. 4261 - 4268 (2007/10/03)
An efficient synthesis of (S,S)-2-(aminomethyl) cyclopropane carboxylic acid has been achieved in 7 steps (38% overall yield) starting from commercially available cinnamyl alcohol. The synthesis involves initial stereoselective formation of the functional
