Check Digit Verification of cas no

The CAS Registry Mumber 156682-50-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,6,8 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 156682-50:
(8*1)+(7*5)+(6*6)+(5*6)+(4*8)+(3*2)+(2*5)+(1*0)=157
157 % 10 = 7
So 156682-50-7 is a valid CAS Registry Number.

Meta-substituted aromatic compounds having six-membered rings, for use in liquid-crystal mixtures

-

, (2008/06/13)

Meta-substituted aromatic compounds having six-membered rings, for use in liquid-crystal mixtures Compounds of the formula I STR1 in which X is CH, CF or N, R2 is, for example, an alkyl, ether or ester group, which may also contain a chiral center, and R1 (--A1)a (--M1)b (--A2)c (--M2) d (--A3)e (--M3)f is a mesogenic radical, can advantageously be used as components of liquid-crystal mixtures, in particular ferroelectric liquid-crystal mixtures. The substances of the formula I have a particularly favorable effect on the optical switching angle and the critical pulse area of the mixtures.
