Check Digit Verification of cas no

The CAS Registry Mumber 54718-68-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,7,1 and 8 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 54718-68:
(7*5)+(6*4)+(5*7)+(4*1)+(3*8)+(2*6)+(1*8)=142
142 % 10 = 2
So 54718-68-2 is a valid CAS Registry Number.

, (2008/06/13)

A material in the form of a film is described which contains, in an orientated arrangement which does not display point symmetry, compounds of formula I STR1 wherein X is =CH-- or =N--, R1 is C12 -C30 -alkyl, R2 is hydrogen or C1 -C30 -alkyl, R3 is --NO2, --CN, --CF3, --COCF3, --SO2 CH3 or --SO2 CF3, R4 is hydrogen or is defined in the same way as R3, R5 is hydrogen or --NR6 R7 and R6 and R7 independently of one another are hydrogen or C1 -C30 -alkyl, it also being possible for any of the alkyl radicals to be partially fluorinated or perfluorinated. The compounds of formula I can be arranged in Langmuir-Blodgett layer systems. Such systems can be used for example for the manufacture of opto-electronic units.
