42877-15-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 42877-15-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,8,7 and 7 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 42877-15:
(7*4)+(6*2)+(5*8)+(4*7)+(3*7)+(2*1)+(1*5)=136
136 % 10 = 6
So 42877-15-6 is a valid CAS Registry Number.

Syntheses of 5-fluoro-D/L-dopa and 5-fluoro-L-dopa
Argentini, Mario,Wiese, Claudia,Weinreich, Regin
, p. 141 - 144 (2007/10/02)
This paper describes the synthesis of 5-fluoro-D/L-dopa and the corresponding 5-fluoro-L-dopa starting from 5-nitrovanillin via malonic ester synthesis, the Balz-Schiemann reaction and the separation of the racemic mixture 5-fluoro-D/L-dopa
