Check Digit Verification of cas no

The CAS Registry Mumber 1598412-40-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,9,8,4,1 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1598412-40:
(9*1)+(8*5)+(7*9)+(6*8)+(5*4)+(4*1)+(3*2)+(2*4)+(1*0)=198
198 % 10 = 8
So 1598412-40-8 is a valid CAS Registry Number.

Fine tuning of frontier orbital energy levels in dithieno[3,2-b:2′, 3′-d]silole-based copolymers based on the substituent effect of phenyl pendants

, p. 2139 - 2145 (2014/05/06)

A series of dithieno[3,2-b:2′,3′-d]silole-based π-conjugated copolymers containing thieno[3,4-c]pyrrole-4,6-dione or thieno[3,4-b]thiophene units bearing 4-substituted phenyl pendants were synthesized and their thermal stability, optical properties and frontier orbital energy levels were systematically investigated. The introduction of electron-withdrawing substituents on the phenyl rings lowered their frontier orbital energy levels without deteriorating their thermal and optical properties. By replacing an electron-donating methoxy group with an electron-withdrawing trifluoromethyl group, both the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital energy levels of the polymers were deepened by more than 0.3 eV. A relatively linear relationship was observed between the HOMO energy levels and the Hammett substituent constants.
