1206691-16-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1206691-16-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,6,6,9 and 1 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1206691-16:
(9*1)+(8*2)+(7*0)+(6*6)+(5*6)+(4*9)+(3*1)+(2*1)+(1*6)=138
138 % 10 = 8
So 1206691-16-8 is a valid CAS Registry Number.

, p. 856 - 863 (2010)
(Chemical Equation Presented) Three meso-substituted bisanthenes, 4-6, were prepared in a short synthetic route from the bisanthenequinone. They exhibit largely improved stability and solubility in comparison to the parent bisanthene. All of these compoun
