211430-90-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 211430-90-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,1,4,3 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 211430-90:
(8*2)+(7*1)+(6*1)+(5*4)+(4*3)+(3*0)+(2*9)+(1*0)=79
79 % 10 = 9
So 211430-90-9 is a valid CAS Registry Number.

New fused lactones from indolizinediones via N-acyliminium ions
Othman, Mohamed,Pigeon, Pascal,Decroix, Bernard
, p. 8737 - 8744 (2007/10/03)
N-Arylmethylphthalimidine-3-carboxylates 3 are good precursors for the synthesis of ketones 5a,b or enols 6c-e which upon acidic treatment led to lactones 7 via an N-acyliminium ion.
