Check Digit Verification of cas no

The CAS Registry Mumber 27472-31-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,4,7 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 27472-31:
(7*2)+(6*7)+(5*4)+(4*7)+(3*2)+(2*3)+(1*1)=117
117 % 10 = 7
So 27472-31-7 is a valid CAS Registry Number.

PHOTOACTIVABLE FLUOROPHORENES. 2. SYNTHESIS AND PHOTOACTIVATION OF FUNCTIONALIZED 3-AROYL-2-(2-FURYL)-CHROMONES

Cummings, Richard T.,DiZio, James P.,Krafft, Grant A.

, p. 69 - 72 (2007/10/02)

The synthesis and photochemistry of functionalized 3-aroyl-2-(2-furyl)-chromones 1 which are photoactivable fluorophores are described.Irradiation converts the non-fluorescent furyl chromones to highly fluorescent 1-arylfuro chromones 3.Functionality has been incorporated to permit covalent attachment, impart aqueous solubility and to maximize the fluorescence of the ultimate 1-arylfurochromone fluorophore.An efficient synthetic pathway to the furyl chromones via an intramolecular Dieckman cyclization also is described.
