1245223-33-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1245223-33-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,5,2,2 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1245223-33:
(9*1)+(8*2)+(7*4)+(6*5)+(5*2)+(4*2)+(3*3)+(2*3)+(1*3)=119
119 % 10 = 9
So 1245223-33-9 is a valid CAS Registry Number.

Rhodium-catalyzed carbometalation of ynamides with organoboron reagents
Gourdet, Benoit,Smith, Donna L.,Lam, Hon Wai
experimental part, p. 6026 - 6031 (2010/09/10)
In the presence of catalytic [Rh(cod)(MeCN)2]BF4, ynamides undergo carbometalation with boronic acids, arylboronic esters, and triarylboroxines. These reactions enable the regio- and stereocontrolled synthesis of multisubstituted ena
