148172-28-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 148172-28-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,8,1,7 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 148172-28:
(8*1)+(7*4)+(6*8)+(5*1)+(4*7)+(3*2)+(2*2)+(1*8)=135
135 % 10 = 5
So 148172-28-5 is a valid CAS Registry Number.

Synthesis, Liquid Crystals and Photochemistry of Di- and Tristyrylbenzenes with Alkoxy Side Chains
Zerban, Georg,Meier, Herbert
, p. 171 - 184 (2007/10/02)
The all-(E)-configurated distyrylbenzenes 4a-g and 1,3,5-tristyrylbenzenes 6a,b,g were prepared by stereoselective condensation reactions of azomethines 2 and methylarenes 3 and 4, respectively. 4a,b,d and e generate light sensitive liquid crystals due to
