139237-90-4 Usage
General Description
The chemical "(1R,3S)-3-[(Z)-2-chloro-3,3,3-trifluoro-prop-1-enyl]-2,2-dimethyl-cyclopropane-1-carbonyl chloride" is a compound with a cyclopropane ring and a carbonyl chloride functional group. It has a chlorine atom and three fluorine atoms attached to a double bond, giving it a highly electronegative and reactive nature. The Z configuration of the double bond indicates a specific stereochemistry, while the presence of the carbonyl chloride group suggests that it can be used as a reactive intermediate in organic synthesis, particularly in the formation of esters or amides. The compound's unique structure and reactivity make it potentially useful in medicinal chemistry, agrochemicals, or materials science.
Check Digit Verification of cas no
The CAS Registry Mumber 139237-90-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,2,3 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 139237-90:
(8*1)+(7*3)+(6*9)+(5*2)+(4*3)+(3*7)+(2*9)+(1*0)=144
144 % 10 = 4
So 139237-90-4 is a valid CAS Registry Number.
