Check Digit Verification of cas no

The CAS Registry Mumber 389573-07-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,8,9,5,7 and 3 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 389573-07:
(8*3)+(7*8)+(6*9)+(5*5)+(4*7)+(3*3)+(2*0)+(1*7)=203
203 % 10 = 3
So 389573-07-3 is a valid CAS Registry Number.

Trans-1,2-difluorostilbenes: Promising materials for high dielectric biaxiality ferroelectric mixtures

Goodby, John W.,Hindmarsh, Paul,Hird, Michael,Lewis, Robert A.,Toyne, Kenneth J.

, p. 889 - 898 (2001)

A range of two- and three-ring liquid crystals have been synthesised that incorporate a trans-1,2-difluoroethene linking group. Some of the materials have surprisingly low melting points and high smectic C phase stability, and they exhibit the ideal phase
