Check Digit Verification of cas no
The CAS Registry Mumber 129-40-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 129-40:
(5*1)+(4*2)+(3*9)+(2*4)+(1*0)=48
48 % 10 = 8
So 129-40-8 is a valid CAS Registry Number.

Highly fluorescent 1-phenylnaphthindol-6(2H)-one (3b) and its 7-chloro and 7-amino derivatives were synthesized by reaction of 1-aminoanthraquinone with benzyl chloride in KOH-DMSO system, followed by treatment with aluminium chloride.The compound 3b was easily N-alkylated with various alkyl halides in KOH-DMSO system.The fluorescence quantum yields (Φf) of naphthindol-6(2H)-one derivatives 3 were high (0.5-0.7), except for 7-amino derivatives which did not fluoresce.The Φf of 7-chloro derivative (3d) was strongly dependent on solvent: 0.37 in ethanol; 0.02 in acetonitrile; 0 in benzene.The compounds 3 were demonstrated to be efficient laser dyes for 500-550 nm region.
