1349067-53-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1349067-53-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,9,0,6 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1349067-53:
(9*1)+(8*3)+(7*4)+(6*9)+(5*0)+(4*6)+(3*7)+(2*5)+(1*3)=173
173 % 10 = 3
So 1349067-53-3 is a valid CAS Registry Number.

Synthesis of the asperparaline core by a radical cascade
Crick, Peter J.,Simpkins, Nigel S.,Highton, Adrian
, p. 6472 - 6475 (2012/02/15)
A concise access to the pentacyclic core structure of the asperparalines is described. The key step is a radical cascade sequence comprised of a 1,6-hydrogen atom transfer followed by 6exo-trig and 5exo-trig cyclizations.
