Check Digit Verification of cas no

The CAS Registry Mumber 1189397-90-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,9,3,9 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1189397-90:
(9*1)+(8*1)+(7*8)+(6*9)+(5*3)+(4*9)+(3*7)+(2*9)+(1*0)=217
217 % 10 = 7
So 1189397-90-7 is a valid CAS Registry Number.

Synthesis and mesomorphic properties of two series of laterally fluorinated symmetric ester liquid crystals

Wei, Qiang,Yuan, Xiaotao,Zhang, Lipei,Wang, Liping,Yang, Huai,Wang, Yangbin

experimental part, p. 52 - 60 (2010/03/25)

Two series of symmetric ester liquid crystals (nAFBHQ and nADFBHQ) with lateral fluorine atoms have been synthesized. Their chemical structures were measured by FTIR, 1H NMR, and elemental analysis (EA). Their mesomorphic properties were investigated by d
