Check Digit Verification of cas no

The CAS Registry Mumber 15125-93-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,1,2 and 5 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 15125-93:
(7*1)+(6*5)+(5*1)+(4*2)+(3*5)+(2*9)+(1*3)=86
86 % 10 = 6
So 15125-93-6 is a valid CAS Registry Number.

Synthesis and electro-optical evaluation of 2,6-bis(arylethynyl)anthraxquinones

Tumuluri, Anusha,Khanna, Bhanupriya,Altalib, Ammar,Revell, Kevin D.

, p. 337 - 343 (2015/06/22)

A series of 2,6-bis(arylethynyl)anthraquinones was prepared via double Sonogashira coupling to 2,6-diiodoanthraquinone, and characterized with regard to their optical and electronic properties. Substitution with a derivatized phenylethynyl group produced a λonset of 366 nm (Eg = 3.4 eV), but the more highly conjugated 2,6-bis(9'-anthracylethynyl)anthraquinones exhibited a λonset of approximately 540 nm (Eg = 2.3 eV). Poor solubility in the unsubstituted 9'-anthracylethynyl system hampered complete characterization or purification, but the 10'-hexanoylanthrac-9'-ylethynyl analog exhibited significantly better solubility. The preparation of several other functionalized derivatives was also explored, and key synthetic findings are reported.
