157718-86-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 157718-86-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,7,1 and 8 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 157718-86:
(8*1)+(7*5)+(6*7)+(5*7)+(4*1)+(3*8)+(2*8)+(1*6)=170
170 % 10 = 0
So 157718-86-0 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.
