1227745-56-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1227745-56-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,7,7,4 and 5 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1227745-56:
(9*1)+(8*2)+(7*2)+(6*7)+(5*7)+(4*4)+(3*5)+(2*5)+(1*6)=163
163 % 10 = 3
So 1227745-56-3 is a valid CAS Registry Number.

Palladium-catalyzed construction of poly-substituted indolizinones
Cho, Hanyang,Kim, Ikyon
experimental part, p. 5464 - 5480 (2012/09/08)
We have developed a highly efficient one-pot approach to poly-substituted indolizinones from tertiary propargylic alcohols by using a palladium-catalyzed domino reaction. This reaction is proposed to proceed via successive aminopalladation, reductive elim
