141042-21-9 Usage
General Description
Cis-2-fluorocyclopropylaminetosylate is an organic compound that contains a fluorine atom and a cyclopropyl group. The compound is a tosylate, which means it is derived from toluenesulfonic acid, commonly used as a protecting group in organic chemistry. The presence of the fluorocyclopropyl group makes this compound a potentially valuable building block for the synthesis of pharmaceuticals and other organic compounds, as both the fluorine and cyclopropyl groups are known for their ability to influence the properties and reactivity of the molecule. The tosylate functional group also provides a versatile handle for further chemical modifications, making this compound a potentially valuable intermediate for synthetic chemistry applications.
Check Digit Verification of cas no
The CAS Registry Mumber 141042-21-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,0,4 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 141042-21:
(8*1)+(7*4)+(6*1)+(5*0)+(4*4)+(3*2)+(2*2)+(1*1)=69
69 % 10 = 9
So 141042-21-9 is a valid CAS Registry Number.
