Cyclopentaneacetaldehyde, 2-methylene-, also known as 2-methylenecyclopentaneacetaldehyde, is an organic compound with the molecular formula C7H10O. It is a colorless liquid with a pungent odor and is derived from cyclopentane, an alkane with five carbon atoms in a ring structure. This chemical is characterized by the presence of a methylene group (-CH2-) and an aldehyde group (-CHO) attached to the cyclopentane ring. It is used as an intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other organic compounds. Due to its reactive nature, it is typically handled with care and stored under controlled conditions to prevent unwanted reactions or decomposition.

3991-34-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 3991-34-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,9 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.Calculate Digit Verification of CAS Registry Number 3991-34:
(6*3)+(5*9)+(4*9)+(3*1)+(2*3)+(1*4)=112
112 % 10 = 2
So 3991-34-2 is a valid CAS Registry Number.
