Check Digit Verification of cas no

The CAS Registry Mumber 845729-99-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,5,7,2 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 845729-99:
(8*8)+(7*4)+(6*5)+(5*7)+(4*2)+(3*9)+(2*9)+(1*9)=219
219 % 10 = 9
So 845729-99-9 is a valid CAS Registry Number.

Chlorosulphonation of 2-anilino-1,4-naphthoquinone and synthesis of newer sulphonyl derivatives

Berghot, Moged A.,Almuaikel, Nayef S.

, p. 1907 - 1922 (2004)

Synthesis of 2-anilino-1,4-napthoquinone-3-sulphonyl chloride (2) was achieved from the reaction of the title compound with chlorosulphonic acid. The interesting derivative 2 was used as a building block for synthesis of the sulphonyl derivatives 3-24. All these sulphonyl derivatives were characterized by the physical and spectral data (IR, Mass, 1H- and 13C NMR spectra).
