Check Digit Verification of cas no

The CAS Registry Mumber 439610-75-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,9,6,1 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 439610-75:
(8*4)+(7*3)+(6*9)+(5*6)+(4*1)+(3*0)+(2*7)+(1*5)=160
160 % 10 = 0
So 439610-75-0 is a valid CAS Registry Number.

Orthoconic antiferroelectrics. Synthesis and mesomorphic properties of optically active (S)-(+)-4-(1-methylheptyloxycarbonyl)phenyl 4′-(fluoroalkanoyloxyalkoxy)biphenyl-4-carboxylates and 4′-(alkanoyloxyalkoxy)biphenyl-4-carboxylates

Drzewinski,Dabrowski,Czuprynski

, p. 273 - 284 (2007/10/03)

Convenient methods for preparing optically active (S)-(+)-4-(1-methylheptyloxycarbonyl)-phenyl 4′-(ω-perfluoroalkanoyloxyalkoxy)- and 4′-(ω-alkanoyloxyalkoxy)biphenyl-4-carboxylates and their intermediates have been described and discussed. The phase transitions of the prepared esters have been investigated by differential scanning calorimetry.
