Check Digit Verification of cas no

The CAS Registry Mumber 34418-98-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,4,1 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 34418-98:
(7*3)+(6*4)+(5*4)+(4*1)+(3*8)+(2*9)+(1*8)=119
119 % 10 = 9
So 34418-98-9 is a valid CAS Registry Number.

5-Isothiocyanato-1,8-naphthalenedicarbox-4-methylphenylimide, a new fluorescence reagent for compounds containing amino groups (author's transl)

Khalaf,Rimpler

, p. 505 - 511,506,510 (1977)

5-Isothiocyanato-1,3-dioxo-2-p-tolyl-2,3-dihydro-1H-benz[de]isoquinoline (= 5-isothio-cyanato-1,8-naphthalenedicarbox-4-methylphenylimide, compd.5) was synthesized from 1H,3H-naphtho(1,8-cd)pyran-1,3-dione (= 1,8-naphtha-lenedicarboxylic anhydride, compd.1) through nitration, condensation with p-toluidine, reduction with tin(II)-chloride yielding 5-amino-1,3-dioxo-2-p-tolyl-2,3-dihydro-1H-benz(de)isoquino-line (4) as intermediate, and condensation with thiophosgene. Compd. 5 can be used for qualitative and quantitative analyses of compounds containing amino groups.
