1186611-65-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1186611-65-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,6,6,1 and 1 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1186611-65:
(9*1)+(8*1)+(7*8)+(6*6)+(5*6)+(4*1)+(3*1)+(2*6)+(1*5)=163
163 % 10 = 3
So 1186611-65-3 is a valid CAS Registry Number.

Synthesis of thermotropic liquid crystalline polyimides with siloxane linkages
Shoji, Yu,Higashihara, Tomoya,Watanabe, Junji,Ueda, Mitsuru
, p. 716 - 717 (2009)
Thermotropic liquid crystalline (LC) semi-aliphatic polyimides have been developed from 3,3',4,4'-tetracarboxybiphenyl dianhydride (BPDA) and diamines containing siloxane spacer units. These polyimides exhibited high thermal stability and lower transition
