Check Digit Verification of cas no

The CAS Registry Mumber 58635-09-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,6,3 and 5 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 58635-09:
(7*5)+(6*8)+(5*6)+(4*3)+(3*5)+(2*0)+(1*9)=149
149 % 10 = 9
So 58635-09-9 is a valid CAS Registry Number.

Synthesis and Thermal Transitions of Some Liquid Crystalline Oligomers

Chan, W.-C.,Mooney, J. A.,Windle, A. H.

, p. 75 - 88 (2007/10/02)

Fourteen aromatic ester oligomers have been synthesised, the majority of which have not been described previously.They can be considered as model compounds for liquid crystalline polyesters, and as such give useful information regarding the relationship between chemical structure and thermal properties.Such oligomers are also potentially important as precursors to liquid crystalline monomers.
