68809-58-5 Usage
General Description
"1H-Pyrazole-3-carboxylic acid,4-methyl-,methylester(9CI)" is a specific type of chemical compound. It belongs to the class of organic compounds known as pyrazole carboxylic acids and derivatives, which are compounds containing a pyrazole ring substituted at the carbon by a carboxylic acid group. The "4-methyl-" indicates that a methyl group is attached to the 4th carbon atom in the pyrazole ring, and "methylester" means that the carboxylic acid group (-COOH) has reacted with methanol to form a methyl ester (-COOCH3). 1H-Pyrazole-3-carboxylicacid,4-methyl-,methylester(9CI), like many organic compounds, is likely used in chemical research and could potentially be a component of certain pharmaceuticals or synthetic materials. It should only be used by trained professionals due to potential risks associated with chemical handling.
Check Digit Verification of cas no
The CAS Registry Mumber 68809-58-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,8,0 and 9 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 68809-58:
(7*6)+(6*8)+(5*8)+(4*0)+(3*9)+(2*5)+(1*8)=175
175 % 10 = 5
So 68809-58-5 is a valid CAS Registry Number.
