1228045-65-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1228045-65-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,0,4 and 5 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1228045-65:
(9*1)+(8*2)+(7*2)+(6*8)+(5*0)+(4*4)+(3*5)+(2*6)+(1*5)=135
135 % 10 = 5
So 1228045-65-5 is a valid CAS Registry Number.

Rhodium-catalyzed annulation of ynamides with bifunctional arylboron reagents
Gourdet, Benoit,Rudkin, Mairi E.,Lam, Hon Wai
, p. 2554 - 2557 (2010)
Annulation of ynamides with arylboronic acids or esters containing an electrophilic functional group at the ortho-position proceeds under the action of rhodium catalysis to generate 2-amidoindenols or 2-amidoindenes, usually with good regioselectivity.
