395664-68-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 395664-68-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,5,6,6 and 4 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 395664-68:
(8*3)+(7*9)+(6*5)+(5*6)+(4*6)+(3*4)+(2*6)+(1*8)=203
203 % 10 = 3
So 395664-68-3 is a valid CAS Registry Number.

Ring fluorinated thiophenes: Applications to liquid crystal synthesis
Kiryanov, Andre A.,Seed, Alexander J.,Sampson, Paul
, p. 8797 - 8800 (2007/10/03)
Ring fluorinated thiophenes were synthesized via a Balz-Schiemann fluorination approach and were successfully employed in the synthesis of liquid crystals using regioselective electrophilic bromination and regioselective Suzuki coupling chemistry.
