Check Digit Verification of cas no

The CAS Registry Mumber 121943-07-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,9,4 and 3 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 121943-07:
(8*1)+(7*2)+(6*1)+(5*9)+(4*4)+(3*3)+(2*0)+(1*7)=105
105 % 10 = 5
So 121943-07-5 is a valid CAS Registry Number.

11-Chloro-6,11-dihydrodibenzothiepin and its 2-methyl derivative VI were transformed via the 11-(4-(ethoxycarbonyl)-1-piperazinyl) compounds IVc and Vc to 11-(1-piperazinyl) compounds IVb and Vb.Their reactions with 1-(3-chloropropyl)-1,3-dihydro-2H-benzimidazol-2-one (II) afforded the title compounds IVa and IVb.Similar reactions and sequences in the series of 10,11-dihydro-5H-dibenzocycloheptene, 4,9-dihydrothieno-2-benzothiepin, and 10,11-dihydrodibenzothiepin led to further oxatomide (Ia) analogues IIIa and VIIa-XIa.In the test of passivecutaneous anaphylaxis in rats, compound VIIIa was more active than Ia, and IVa had similar activity like Ia.
