General Description

5-CHLORO-1-METHYL-1H-PYRAZOLE-4-CARBONYL CHLORIDE is a chemical compound containing a pyrazole ring with a chloro and methyl substituent at the 5th and 1st position, respectively, and a carbonyl chloride functional group. It is commonly used in organic synthesis as a reagent for the introduction of the 1-methyl-1H-pyrazole-4-carbonyl chloride group into various organic molecules. 5-CHLORO-1-METHYL-1H-PYRAZOLE-4-CARBONYL CHLORIDE is highly reactive and is known for its use in the production of pharmaceuticals, agrochemicals, and other fine chemicals. It is important to handle this compound with caution due to its potential hazards and reactivity.

Check Digit Verification of cas no

The CAS Registry Mumber 110763-09-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,7,6 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 110763-09:
(8*1)+(7*1)+(6*0)+(5*7)+(4*6)+(3*3)+(2*0)+(1*9)=92
92 % 10 = 2
So 110763-09-2 is a valid CAS Registry Number.
