Check Digit Verification of cas no

The CAS Registry Mumber 317351-88-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,7,3,5 and 1 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 317351-88:
(8*3)+(7*1)+(6*7)+(5*3)+(4*5)+(3*1)+(2*8)+(1*8)=135
135 % 10 = 5
So 317351-88-5 is a valid CAS Registry Number.

Synthesis and structure of 1,4-diazabutadiene liquid crystals

Zhao, Ke-Qing,Hu, Pin,Xu, Hong-Bo

, p. 801 - 808 (2007/10/03)

Nine 1,4-diazabutadiene compounds, Ar-N=C(R)-C(R)=N-Ar, R=H, Me; Ar= H2n+1CnO-C6H4, 2,4-(H9C4O)(Me)-C6H3 were synthesized and their liquid crystal properties were studied through thermal polarizing microscopy. The X-ray single crystal structure of compound 9 (Ar-N=C(H)-C(H)=N-Ar, Ar=2,4-(Me)(H9C4O)C6H3) was tested. It is a monoclinic crystal system, space group P21/C with the unit cell parameters: a=7.0703(3)A, b=8.674(4)A, c=18.3115(8)A, β =95.392(1)°. V=1114.57(9)A3, z=2, Dc=1.134 Mg/m3, R=0.0490,Rw=0.1237.
