ETH 2111, also known as 1-(2-methoxyethyl)-4-(3-phenylpropyl)piperazine, is a synthetic psychoactive substance belonging to the piperazine class. It is structurally similar to other piperazine-based drugs, such as benzhydron and pipradrol, and is known for its stimulant and entactogenic effects. ETH 2111 is not approved for medical use and is considered a research chemical, with limited information available on its pharmacology, safety, and potential side effects. Due to its unregulated status and potential risks, it is crucial to exercise caution when considering the use of ETH 2111 or any other research chemicals.
The CAS Registry Mumber 5709-33-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,0 and 9 respectively; the second part has 2 digits, 3 and 3 respectively. Calculate Digit Verification of CAS Registry Number 5709-33: (6*5)+(5*7)+(4*0)+(3*9)+(2*3)+(1*3)=101 101 % 10 = 1 So 5709-33-1 is a valid CAS Registry Number.
