Check Digit Verification of cas no

The CAS Registry Mumber 81221-15-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,2,2 and 1 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 81221-15:
(7*8)+(6*1)+(5*2)+(4*2)+(3*1)+(2*1)+(1*5)=90
90 % 10 = 0
So 81221-15-0 is a valid CAS Registry Number.

Liquid-crystalline Heterocycloalkanes. I. Synthesis and Properties of Substituted 1,3-Dioxanes

Vorbrodt, H.-M.,Deresch, S.,Kresse, H.,Wiegeleben, A.,Demus, D.,Zaschke, H.

, p. 902 - 913 (2007/10/02)

The synthesis of 2,5-disubstituted 1,3-dioxanes is described, their melting and clearing points and their physical properties (dielectric anisotropy, viscosity, transition enthalpies, optical birefringence) are investigated.The cyano substituted 1,3-dioxanes 5 and 7 are valuable materials for application in displays.
