916440-69-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 916440-69-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,6,4,4 and 0 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 916440-69:
(8*9)+(7*1)+(6*6)+(5*4)+(4*4)+(3*0)+(2*6)+(1*9)=172
172 % 10 = 2
So 916440-69-2 is a valid CAS Registry Number.

A synthesis of the welwistatin core
Lauchli, Ryan,Shea, Kenneth J.
, p. 5287 - 5289 (2007/10/03)
An approach to the core structure of the microtubule-targeting agent welwistatin is described. The approach utilizes the type 2 intramolecular Diels-Alder reaction, with indole serving as the tether between diene and dienophile, to form the natural produc
