Check Digit Verification of cas no

The CAS Registry Mumber 473389-93-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,3,3,8 and 9 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 473389-93:
(8*4)+(7*7)+(6*3)+(5*3)+(4*8)+(3*9)+(2*9)+(1*3)=194

Smectic layered polymer networks based on side chain liquid crystalline polymers having thermally reversible urea bonds

Seo, Sang Hyuk,Kim, Young-Woon,Chang, Ji Young

, p. 1525 - 1527 (2005)

The preparation of nanospaced polymer networks from side chain liquid crystalline polymers having thermally reversible urea bonds between the polymers and the pendent mesogenic groups was described. It was observed that the polymers had smectic layered st
