Check Digit Verification of cas no

The CAS Registry Mumber 78659-80-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,6,5 and 9 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 78659-80:
(7*7)+(6*8)+(5*6)+(4*5)+(3*9)+(2*8)+(1*0)=190
190 % 10 = 0
So 78659-80-0 is a valid CAS Registry Number.

Synthesis and spectral-luminescence properties of 4,4′-di(2-oxazolyl)-stilbenes and 4,4′-di(2-oxazolyl)tolans

Vernigor,Shalaev,Luk'yanets

, p. 328 - 332 (2007/10/02)

A new method is proposed for the synthesis of 4,4′-di(2-oxazolyl)stilbenes and 4,4′-di(2-oxazolyl) tolans by condensation of oxazolyl-substituted benzyl bromides or benzal dibromides under the influence of strong bases (KOH, potassium tertbutoxide) in dipolar aprotic solvents [dimethylformamide (DMF) and dimethyl sulfoxide (DMSO)]. The synthesized compounds luminesce intensely over the spectral range 386-492 nm.
