1448042-19-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1448042-19-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,8,0,4 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1448042-19:
(9*1)+(8*4)+(7*4)+(6*8)+(5*0)+(4*4)+(3*2)+(2*1)+(1*9)=150
150 % 10 = 0
So 1448042-19-0 is a valid CAS Registry Number.

Facile chemoselective carbonyl allylation of chalcones with allyltributylstannane catalyzed by CuI
Kalita, Pabitra Kumar,Phukan, Prodeep
, p. 4442 - 4445 (2013)
Chemoselective allylation of carbonyl functionality of chalcones with allyltributylstannane was accomplished in the presence of CuI as catalyst. This reaction works well in DMF at 70 C with exclusive formation of 1,2-addition product. Interesting feature
