Check Digit Verification of cas no

The CAS Registry Mumber 1331841-32-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,1,8,4 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1331841-32:
(9*1)+(8*3)+(7*3)+(6*1)+(5*8)+(4*4)+(3*1)+(2*3)+(1*2)=127
127 % 10 = 7
So 1331841-32-7 is a valid CAS Registry Number.

Characterization and optical properties of novel unsymmetrical stilbene-based 1,3,4-oxadiazole derivatives

He, Dao-Hang,Li, Xin-Wei,Yang, Chong,Yang, Jun

, p. 184 - 187 (2012/07/17)

A series of novel unsymmetrical stilbene-based 1,3,4-oxadiazole derivatives were efficiently synthesized by a four-pots reaction sequence. All of the title compounds were characterized by MS, 1H-NMR and elemental analysis. UV-Vis absorption and fluorescence emission spectra of the compounds were investigated in dilute chloroform solution; the compounds exhibit strong blue-green fluorescence ranged from 397 to 499 nm and show potential for application in organic optical materials.
