Check Digit Verification of cas no

The CAS Registry Mumber 125908-24-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,9,0 and 8 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 125908-24:
(8*1)+(7*2)+(6*5)+(5*9)+(4*0)+(3*8)+(2*2)+(1*4)=129
129 % 10 = 9
So 125908-24-9 is a valid CAS Registry Number.

Studies in spiroheterocycles: Part XI - Synthesis of novel fluorine containing 4',5'-dihydrospirothiadiazepine>-2(1H),5'-diones from isatins

Joshi, Krishna C.,Dandia, Anshu,Ahmed, Nidhal

, p. 639 - 641 (2007/10/02)

Reaction of mercaptoacetic acid with fluorinated 3-aryliminoindol-2-ones, prepared in situ from fluorinated indole-2,3-diones(isatins) and fluorinated anilines, yields 3'-arylspiro-2(1H),4'-diones(I).Under similar conditions, 3-(4-phenylpyrazol-5-ylimino)indol-2-ones(II) yield a novel system 4',5'-dihydro-9'-phenylspirothiadiazepine>-2(1H),5'-dione (III). 3-(4-Phenylpyrazol-5-ylimino)indol-2-ones have been synthesized by the reaction of fluorine containing indole-2,3-diones with 3-amino-4-phenylpyrazole in abs. ethanol.The structures of the compounds have been established on the basis of elemental analyses, and IR, PMR, 19F NMR and mass spectral data.
