902171-51-1 Usage
General Description
4-Methoxy-2-methyl-nicotinonitrile, also known as Tolvaptan intermediate or 4-Methoxy-2-methyl-3-[(2-methyl-1H-indol-3-yl)carbonyl]pyridine, is a chemical compound used in the synthesis of Tolvaptan, a medication used to treat hyponatremia (low sodium levels in the blood) and fluid retention. This intermediate is a key building block in the production of Tolvaptan, which works by blocking the action of vasopressin, a hormone that regulates the body’s water balance. 4-Methoxy-2-methyl-nicotinonitrile is a white to off-white crystalline powder that must be handled and stored carefully due to its potential hazards.
Check Digit Verification of cas no
The CAS Registry Mumber 902171-51-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,2,1,7 and 1 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 902171-51:
(8*9)+(7*0)+(6*2)+(5*1)+(4*7)+(3*1)+(2*5)+(1*1)=131
131 % 10 = 1
So 902171-51-1 is a valid CAS Registry Number.
