Check Digit Verification of cas no
The CAS Registry Mumber 82834-45-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,8,3 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 82834-45:
(7*8)+(6*2)+(5*8)+(4*3)+(3*4)+(2*4)+(1*5)=145
145 % 10 = 5
So 82834-45-5 is a valid CAS Registry Number.

The reactivity of some 5-bromo-2-nitro-3-R-thiophens (Ia-g; R=H, Me, Et, Prn, n-hexyl, Pri, and But), 3,4-dibromo-2-nitro-5-R-thiophens (IIa and b; R=H and Me), 3-bromo-2-nitro-5-R-thiophens (IIIa and b; R=H and Me), and 2-bromo-3-nitro-5-R-thiophens (IVa and b; R=H and Me) with amines and sodium benzenethiolate has been studied in methanol at various temperatures.Piperidinodebromination of compounds (Ia and c) has also been studied in benzene, in dioxan, and in dioxan-water (60:40 and 10:90).Independent of the position of the alkyl group (meta or para with respect to the leaving bromine), an unexpected alkyl activation has been observed, which represents a further exception to the electron-releasing behaviour of alkyl groups.
