467221-23-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 467221-23-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,6,7,2,2 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 467221-23:
(8*4)+(7*6)+(6*7)+(5*2)+(4*2)+(3*1)+(2*2)+(1*3)=144
144 % 10 = 4
So 467221-23-4 is a valid CAS Registry Number.

Synthesis of pyran-4-ones from isoxazoles
Li, Chun-Sing,Lacasse, Edith
, p. 3565 - 3568 (2007/10/03)
A synthesis of mono-, di- and tri-substituted pyran-4-ones from isoxazoles is reported. The isoxazoles can be synthesized from readily available starting materials and undergo a reductive cleavage reaction with Mo(CO)6 to generate enamino keton
