28052-47-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 28052-47-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,0,5 and 2 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 28052-47:
(7*2)+(6*8)+(5*0)+(4*5)+(3*2)+(2*4)+(1*7)=103
103 % 10 = 3
So 28052-47-3 is a valid CAS Registry Number.

New approaches to the asymmetric synthesis of α-methylphenylalanine
Cativiela,Diaz-de-Villegas,Galvez
, p. 261 - 268 (2007/10/02)
A strategy of highly selective alkylation of chiral 2-cyanoesters followed by the corresponding degradation process allows a divergent asymmetric synthesis of (R) and (S)-α-methylphenylalanine.
