691-77-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 691-77-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,9 and 1 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 691-77:
(5*6)+(4*9)+(3*1)+(2*7)+(1*7)=90
90 % 10 = 0
So 691-77-0 is a valid CAS Registry Number.

Synthesis of new β-trifluoromethyl containing GABA and β-fluoromethyl containing N-benzylpyrrolidinones

Gerus, Igor I.,Mironets, Roman V.,Shaitanova, Elena N.,Kukhar, Valery P.

scheme or table, p. 224 - 228 (2010/04/30)

A whole series of 3-(mono-, di-, trifluoro)methyl-substituted N-benzylpyrrolidinones 5a-c was synthesized by deoxyfluorination of corresponding 3-functionalized N-benzylpyrrolidinones. New β-trifluoromethyl containing GABA 4a was obtained in two alternative ways: by successive hydrolysis and hydrogenolysis of 3-trifluoromethyl N-benzylpyrrolidinone 5a and from trifluoroacetone as starting compound.

Antiinflammatory activity of a series of substituted 2,3-dihydro-6-hydroxypyrimido[2,1-f]purine-4,8(1H,9H)-diones
