338995-26-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 338995-26-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,8,9,9 and 5 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 338995-26:
(8*3)+(7*3)+(6*8)+(5*9)+(4*9)+(3*5)+(2*2)+(1*6)=199
199 % 10 = 9
So 338995-26-9 is a valid CAS Registry Number.

Synthesis of New Mesomorphic Polyesters by Polymerization of Bifunctional Monomers
Keller, Patrick
, p. 247 - 256 (2007/10/02)
New polyesters have been synthesized by high temperature polycondensation of bifunctional monomers (4-(ω-(4-acetyloxyphenyloxy)alkyloxy)benzoic acids).Their mesomorphic porperties have been studied.By analogy with the chemistry of polypeptide polymers (us
