75156-82-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 75156-82-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,1,5 and 6 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 75156-82:
(7*7)+(6*5)+(5*1)+(4*5)+(3*6)+(2*8)+(1*2)=140
140 % 10 = 0
So 75156-82-0 is a valid CAS Registry Number.

Condensation of pyrrolidine-2-thione (21) with methyl α-bromo-(2-bromo-4,5-dimethoxyphenyl)acetate (15) gave methyl (Z)-α-(2-bromo-4,5-dimethoxyphenyl)-α-pyrrolidin-2-ylideneacetate (25) in high yield.Several other methyl (Z)-α-aryl-α-acetates (26)-(31) were also synthesised in good yields from reaction of the corresponding phenylacetates (15), (12), and (13) with trans-3-acetoxy-4-(N-ethoxycarbonyl-N-methylamino)pyrrolidine-2-thione (20).Treatment of compounds (25)-(31) with sodium hydride and copper(I) bromide in dimethylformamide afforded methyl 2,3-dihydro-6,7-dimethoxy-1H-pyrroloindole-9-carboxylate (34) and the methyl (+/-)-trans-1-acetoxy-2-(N-ethoxycarbonyl-N-methylamino)-2,3-dihydro-1H-pyrroloindole-9-carboxylates (35)-(37) in good yields.Methyl (+/-)-trans-1-acethoxy-2-(N-ethoxycarbonyl-N-methylamino)-2,3-dihydro-7-methoxy-6-methyl-1H-pyrroloindole-9-carboxylate (36) was converted into the 5,8-quinone (3), via the 8-nitro-compound (38).
