80419-42-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80419-42-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,4,1 and 9 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 80419-42:
(7*8)+(6*0)+(5*4)+(4*1)+(3*9)+(2*4)+(1*2)=117
117 % 10 = 7
So 80419-42-7 is a valid CAS Registry Number.

Synthesis and Properties of Trimethinecyanines with Bridged Chains
Fanghaenel, E.,Behrmann, K.,Bach, G.
, p. 811 - 822 (2007/10/02)
The effects of meso-substituents (H, morpholino, ethoxy) and hydrogencarbon bridges, on the light absorption and the electrochemical properties of trimethyinecyanine dyes (4a-f, 8a-c, 10a-f) are investigated.The results are in good agreement with the pred
