Check Digit Verification of cas no

The CAS Registry Mumber 103724-87-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,7,2 and 4 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 103724-87:
(8*1)+(7*0)+(6*3)+(5*7)+(4*2)+(3*4)+(2*8)+(1*7)=104
104 % 10 = 4
So 103724-87-4 is a valid CAS Registry Number.

Carbamate series of juvenoids: Variation of the O-alkyl substituent

Wimmer,Saman,Nemec,Francke

, p. 561 - 568 (2007/10/02)

By changing the O-alkyl substituents of the carbamate moiety of alkyl N-{2-{4-[(2-oxocyclohexyl)methyl]phenoxy}ethyl}carbamates and subsequent transformation of the oxo group in the cyclohexyl substituent, the juvenoids 1-20 were synthesized (Scheme). The methyl (1-4), propyl (9-12), isopropyl (13-16), and prop-2-ynylcarbamates (17-20) were subjected to biological screening on several non-related insect species (Tenebrio molitor, Galleria mellonella, Dysdercus cingulatus, and Pyrrhocoris apterus). Some of the juvenoids showed high biological activity and excellent selectivity with respect to target insect species (Table 2).
