Check Digit Verification of cas no

The CAS Registry Mumber 4402-78-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,0 and 2 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4402-78:
(6*4)+(5*4)+(4*0)+(3*2)+(2*7)+(1*8)=72
72 % 10 = 2
So 4402-78-2 is a valid CAS Registry Number.

A series of novel ethyl 2-(5-methyl-3-arylisoxazole-4-carboxamido)-4-alkylthiazole-5-carboxylates I-1-6 were synthesized. The structures of all target compounds were characterized by 1H NMR, 13C NMR, IR,MS and elemental analyses. Their fungicidal and herbicidal activities were evaluated. The results of preliminary bioassays show that the title compounds I-4 possess 20-50% inhibition against most of the tested plants at the dosage of 150 g ai/ha, while the title compounds I-1-5 possess 32-58% inhibition against FusaHum graminearum, Thanatephorus cucumeris, Botrytis cinereapers and Fusarium oxysporum in vitro at the concentration of 100 mg/L.
