90329-50-3 Usage
General Description
5-ethyl-1-methyl-1H-tetrazole is a chemical compound with the chemical formula C5H10N4. It is a white to off-white solid that is insoluble in water but soluble in organic solvents. 5-ETHYL-1-METHYL-1H-TETRAZOLE is used as a pharmaceutical intermediate, specifically in the synthesis of various drugs including candesartan, an angiotensin II receptor antagonist used for the treatment of hypertension. It is also used as a stabilizer in the synthesis of explosives and as an inhibitor in corrosion prevention. 5-ethyl-1-methyl-1H-tetrazole has a molecular weight of 122.16 g/mol and is classified as a hazardous substance, requiring proper handling and storage.
Check Digit Verification of cas no
The CAS Registry Mumber 90329-50-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,3,2 and 9 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 90329-50:
(7*9)+(6*0)+(5*3)+(4*2)+(3*9)+(2*5)+(1*0)=123
123 % 10 = 3
So 90329-50-3 is a valid CAS Registry Number.
