1449232-80-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1449232-80-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,9,2,3 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1449232-80:
(9*1)+(8*4)+(7*4)+(6*9)+(5*2)+(4*3)+(3*2)+(2*8)+(1*0)=167
167 % 10 = 7
So 1449232-80-7 is a valid CAS Registry Number.

Lewis base directed cycloaddition reactions of 2-pyrones and alkynylaluminum reagents
Crepin, Damien F.,Harrity, Joseph P. A.
, p. 4222 - 4225 (2013/09/12)
In situ generated alkynylaluminum reagents have been utilized in a [4 + 2] cycloaddition with 2-pyrones bearing a Lewis basic donor. The reactions proceed at or below room temperature and with complete regiocontrol. This one-pot method affords diversely s
