(R)-(1'-phenylethyl)-4-oxo-6-phenylhexanamide, also known as 4-KPH, is a synthetic derivative of cathinone, a natural amphetamine found in the khat plant. It is a chemical compound with a molecular formula C20H23NO2 and possesses psychoactive properties. As a monoamine releasing agent, it increases the levels of neurotransmitters such as dopamine, serotonin, and norepinephrine in the brain, leading to stimulant effects. Due to its psychoactive nature, 4-KPH is considered a controlled substance in many countries and is not approved for medical use.

Check Digit Verification of cas no

The CAS Registry Mumber 159757-42-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,7,5 and 7 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 159757-42:
(8*1)+(7*5)+(6*9)+(5*7)+(4*5)+(3*7)+(2*4)+(1*2)=183
183 % 10 = 3
So 159757-42-3 is a valid CAS Registry Number.
