Check Digit Verification of cas no
The CAS Registry Mumber 71902-18-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,9,0 and 2 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 71902-18:
(7*7)+(6*1)+(5*9)+(4*0)+(3*2)+(2*1)+(1*8)=116
116 % 10 = 6
So 71902-18-6 is a valid CAS Registry Number.

PIGMENT DISPERSION, AND RESIST COMPOSITION FOR COLOR FILTER AND INK COMPOSITION EACH USING THE PIGMENT DISPERSION
-
Paragraph 0074; 0084, (2013/03/26)
To provide a pigment dispersion excellent in dispersibility and spectral characteristics. The pigment dispersion at least includes: a dispersion medium; a compound represented by a general formula (1), the compound being dispersed in the dispersion medium; and a pigment having a quinacridone skeleton, the pigment being dispersed in the dispersion medium: General formula (1) in the general formula (1), R1 and R2 each independently represent a hydrogen atom, an alkyl group, an aryl group, or an aralkyl group.
