1246384-80-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1246384-80-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,6,3,8 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1246384-80:
(9*1)+(8*2)+(7*4)+(6*6)+(5*3)+(4*8)+(3*4)+(2*8)+(1*0)=164
164 % 10 = 4
So 1246384-80-4 is a valid CAS Registry Number.

An improved protocol for Petasis reaction of 2-pyridinecarbaldehydes
Mandai, Hiroki,Murota, Kyouta,Sakai, Takashi
, p. 4779 - 4782 (2010)
A highly efficient and improved method has been developed for Petasis reactions of various 2-pyridinecarbaldehydes with secondary amines and boronic acids under catalyst-free conditions. The desired products are obtained in up to 96% yield in refluxed acetonitrile.
