74743-93-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 74743-93-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,7,4 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 74743-93:
(7*7)+(6*4)+(5*7)+(4*4)+(3*3)+(2*9)+(1*3)=154
154 % 10 = 4
So 74743-93-4 is a valid CAS Registry Number.

Synthesis of (R)-5-Aminohex-2-enedioic acid and the (+/-)-2-Bromo Derivative as Unsaturated Analogues of the Neurotransmitter Antagonist D-&α-Aminoadipic Acid

Allan, Robin D.

, p. 4658 - 4667 (2007/10/02)

5-Aminohex-2-enedioic acid (2), an unsaturated analogue of the neurotransmitter antagonist D-α-aminoadipic acid, has been synthesised by a convenient route using a phase-transfer alkylation of N-diphenylmethyleneglycine ethyl ester.The unsaturated amino acid has been resolved and the absolute stereochemistry of the (-) isomer determined as R by reduction to D-α-aminoadipic acid.A more conventional synthetic scheme failed to yield (2), but led to the preparation of the (+/-)-2-bromo derivative (4) in low yield.
