77443-41-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77443-41-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,4,4 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 77443-41:
(7*7)+(6*7)+(5*4)+(4*4)+(3*3)+(2*4)+(1*1)=145
145 % 10 = 5
So 77443-41-5 is a valid CAS Registry Number.

Facile Racemization of N-Acylated α-Amino-γ-lactones
Michl, Kurt
, p. 33 - 39 (2007/10/02)
The lactones of L-γ-hydroxyamino acids are essential components of all toxins of the green deathcap mushroom, Amanita phalloides.N-Acylated derivatives (2a-g), as α-amino-γ-lactones (type 1), racemize at the α-C atom even under weakly basic conditions on
