887945-65-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 887945-65-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,7,9,4 and 5 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 887945-65:
(8*8)+(7*8)+(6*7)+(5*9)+(4*4)+(3*5)+(2*6)+(1*5)=255
255 % 10 = 5
So 887945-65-5 is a valid CAS Registry Number.

Synthesis of indoles via 6π-electrocyclic ring closures of trienecarbamates
Greshock, Thomas J.,Funk, Raymond L.
, p. 4946 - 4947 (2007/10/03)
A new method for the preparation of indoles from readily available α-haloenones and α-(trialkylstannyl)enecarbamates is described. Following a Stille coupling, trienecarbamate 2 is electronically activated to undergo a facile 6π-electrocyclic ring closure
