118331-19-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 118331-19-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,3,3 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 118331-19:
(8*1)+(7*1)+(6*8)+(5*3)+(4*3)+(3*1)+(2*1)+(1*9)=104
104 % 10 = 4
So 118331-19-4 is a valid CAS Registry Number.

1,3,9,11,12,14-Hexa-azapentacene-2,4,8,10(3H,9H,12H,14H,)-tetraones (Doubled 5-Deazaflavins) with Potencial for Oxido Reduction

, p. 1809 - 1812 (2007/10/02)

Condensation of 8-(substitued-amino)1,5-dihydro-5-deazaflavins (3) with 6-chloro-5-formyluracils (4) gave the 1,5-dihydro doubled 5-deazaflavins (5) and 8-(5-formyluracil-6-yl)amino-1,5-dihydro-5-deazaflavins (6).The dehydrogenation of compounds (5) with diethyl azodicarboxylate or the dehydrative cyclization of compounds (6) with Vilsmeier reagent gave the corresponding 1,3,9,11,12,14-hexa-azapentacene-2,4,8,10(3H,9H,12H,14H)-tetraones (doubled 5-deazaflavins) (8).The latter exhibited strong autorecycling oxidation toward cyclopentanol giving, in sunlight under an oxygen atmosphere, cyclopentanone
