196397-50-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 196397-50-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,6,3,9 and 7 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 196397-50:
(8*1)+(7*9)+(6*6)+(5*3)+(4*9)+(3*7)+(2*5)+(1*0)=189
189 % 10 = 9
So 196397-50-9 is a valid CAS Registry Number.

Asymmetric total synthesis of (+)-carbocyclic uracil polyoxin C
Aggarwal, Varinder K.,Monteiro, Nuno
, p. 2531 - 2537 (2007/10/03)
A short, practical, asymmetric synthesis of carbocyclic uracil polyoxin C is described. The key step in the synthesis is a regio- and stereo-selective palladium-mediated substitution reaction of an α-amino substituted unsaturated lactone with bis-silylate
