Check Digit Verification of cas no

The CAS Registry Mumber 1631160-91-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,1,1,6 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1631160-91:
(9*1)+(8*6)+(7*3)+(6*1)+(5*1)+(4*6)+(3*0)+(2*9)+(1*1)=132
132 % 10 = 2
So 1631160-91-2 is a valid CAS Registry Number.

Arylethynyl-substituted tristriazolotriazines: Synthesis, optical properties, and thermotropic behavior

Glang, Stefan,Rieth, Thorsten,Borchmann, Dorothee,Fortunati, Ilaria,Signorini, Raffaella,Detert, Heiner

, p. 3116 - 3126 (2014/06/09)

The synthesis of C3-symmetrical tristriazolotriazines with conjugated arms and lateral alkoxy side chains was performed by a threefold condensation of cyanuric chloride with tetrazoles. Conjugated π segments include phenyl, tolane, and its phenylethynyl-elongated homologue. Disclike and a dendritic molecule have been obtained, and two compounds with a 3,4,5-tris(octyloxy) substitution form broad thermotropic mesophases. The linear optical properties, solvatochromism of the fluorescence, acidochromism, and the two-photon absorption efficiency of selected compounds are reported. Copyright
