Check Digit Verification of cas no

The CAS Registry Mumber 1224288-66-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,4,2,8 and 8 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1224288-66:
(9*1)+(8*2)+(7*2)+(6*4)+(5*2)+(4*8)+(3*8)+(2*6)+(1*6)=147
147 % 10 = 7
So 1224288-66-7 is a valid CAS Registry Number.

Synthesis of some new pyrazole and pyrimidine derivatives carrying a sulfonamide moiety of expected antitumor activity and study of the synergistic effect of γ-irradiation

Ghorab, Mostafa M.,Ragab, Fatma A.,Heiba, Helmy I.,Youssef, Hanan A.,Galal, Marwa

experimental part, p. 48 - 55 (2010/04/24)

Several novel pyrazole (11-18) and pyrimidine (19-23) derivatives were synthesized starting from different sulfonamides and different active methylenes. The synthesized compounds were characterized by elemental analysis, IR, 1H-NMR and mass spectral data. The obtained compounds were screened as antitumor agents against human tumor cell line. Some of the tested compounds were equipotent while the others were more potent than doxorubicin (CAS 25316-40-9). The synergistic effect with γ-radiation was also studied.
