149221-14-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 149221-14-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,2,2 and 1 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 149221-14:
(8*1)+(7*4)+(6*9)+(5*2)+(4*2)+(3*1)+(2*1)+(1*4)=117
117 % 10 = 7
So 149221-14-7 is a valid CAS Registry Number.

Ultraviolet spectroscopy of anticonvulsant enaminones.
Edafiogho, Ivan O,Phillips,Abdel-Hamid,Ali,Matowe,El-Hashim,Kombian
, p. 593 - 597 (2007/10/03)
The ultraviolet (UV) spectra of selected enaminones were determined in acidic, alkaline and neutral media and compared to their anticonvulsant activities. The wavelength of maximum absorption and molar absorptivity were compared with the anticonvulsant ac
