Check Digit Verification of cas no

The CAS Registry Mumber 71458-09-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,4,5 and 8 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 71458-09:
(7*7)+(6*1)+(5*4)+(4*5)+(3*8)+(2*0)+(1*9)=128
128 % 10 = 8
So 71458-09-8 is a valid CAS Registry Number.

The Properties of Liquid Crystal Materials Incorporating the -CH2O- Inter-ring Linkage

Carr, N.,Gray, G. W.

, p. 27 - 44 (2007/10/02)

To establish more securely the influence of the -CH2O- inter-ring linkage upon the properties of mesogens of both high and low dielectric anisotropy, a range of ethers with the following general structure has been prepared and their properties examined. The thermal and electro-optic properties of the compounds are discussed, and comparisons made where possible with analogous materials incorporating the -CH2CH2- linkage.
