14221-84-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 14221-84-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,2,2 and 1 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 14221-84:
(7*1)+(6*4)+(5*2)+(4*2)+(3*1)+(2*8)+(1*4)=72
72 % 10 = 2
So 14221-84-2 is a valid CAS Registry Number.

Synthesis and Reaction of 3-Bromoflavanones with DMSO
Sharma, T. C.,Pawar, S. R.,Reddy, N. J.,Donnelly, John A.
, p. 80 - 81 (2007/10/02)
Bromination of flavanones (I) with (2-carboxyethyl)triphenylphosphonium perbromide gives the corresponding 3-bromoflavanones (II) which when treated with DMSO at room temperature undergo dehydrobromination to flavones (III).
