Cocaine is a powerful and highly addictive stimulant drug derived from the leaves of the coca plant, native to South America. It is classified as an illegal substance in most countries due to its potential for abuse and severe health risks. Chemically, cocaine is a tropane alkaloid with the molecular formula C17H21NO4, and it exerts its effects by blocking the reuptake of dopamine, norepinephrine, and serotonin in the brain, leading to increased levels of these neurotransmitters and resulting in the characteristic euphoria and increased energy associated with its use. However, chronic use can lead to addiction, severe health issues, and even death.
The CAS Registry Mumber 7058-74-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,0,5 and 8 respectively; the second part has 2 digits, 7 and 4 respectively. Calculate Digit Verification of CAS Registry Number 7058-74: (6*7)+(5*0)+(4*5)+(3*8)+(2*7)+(1*4)=104 104 % 10 = 4 So 7058-74-4 is a valid CAS Registry Number.
