741259-17-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 741259-17-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,1,2,5 and 9 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 741259-17:
(8*7)+(7*4)+(6*1)+(5*2)+(4*5)+(3*9)+(2*1)+(1*7)=156
156 % 10 = 6
So 741259-17-6 is a valid CAS Registry Number.

Synthesis of highly conjugated two-dimensional molecular scaffolds via Pd-catalyzed reactions on a tetraphenylethylene core
Sengupta, Saumitra
, p. 1191 - 1194 (2004)
A facile synthesis of ethylene centered highly conjugated two-dimensional molecular scaffolds is described via Pd-catalyzed coupling reactions (Sonogashira and Heck reactions) on a tetraphenylethylene core.
