1431973-96-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1431973-96-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,1,9,7 and 3 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1431973-96:
(9*1)+(8*4)+(7*3)+(6*1)+(5*9)+(4*7)+(3*3)+(2*9)+(1*6)=174
174 % 10 = 4
So 1431973-96-4 is a valid CAS Registry Number.

Cobalt-catalyzed ortho-alkenylation of aromatic aldimines via chelation-assisted C-H bond activation
Yamakawa, Takeshi,Yoshikai, Naohiko
, p. 4459 - 4465 (2013/06/26)
An ortho-alkenylation reaction of an aromatic aldimine with an internal alkyne is efficiently promoted by a cobalt catalyst generated from CoBr 2, triarylphosphine, and iPrMgBr. The reaction takes place under mild room-temperature co
