Check Digit Verification of cas no

The CAS Registry Mumber 78924-18-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,9,2 and 4 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 78924-18:
(7*7)+(6*8)+(5*9)+(4*2)+(3*4)+(2*1)+(1*8)=172
172 % 10 = 2
So 78924-18-2 is a valid CAS Registry Number.

Synthesis of a series of new N1-[4-(4-nitrophenylthio)phenyl]-N3-(H/alkyl/acyl/aryl) thioureas and their antifungal, insecticidal and larvicidal activities

Shankar,Pandeya

, p. 753 - 756 (2007/10/02)

A series of new mono and disubstituted thioureas, derived from 4-(4-nitrophenylthio) aniline, have been prepared and screened for antifungal activity against Alternaria alternata and Curvularia lunata. Their insecticidal and larvicidal activities have also been evaluated against adult male and female cockroaches (Periplanata americana) and mosquito larvae (Culex pipiens fatigans Wied) of IIIrd and early IVth instar stage, respectively. The tabulated results reveal that most of the thiourea derivatives, in general, possess marked antifungal, insecticidal and larvicidal properties, but the chlorosubstituted derivatives, in particular, are the most active compounds in the entire series. Compound 20, n1-[4-(4-nitrophenylthio)phenyl]-N3-(4-chlorophenyl) thiourea, was the most active antifungal compound, whereas, compound 12, N1[4-(4-nitrophenylthio)phenyl]-N3-(4-chlorobenzoyl) thiourea, was the most potent insecticidal and larvicidal compound.
