Cis-3,4-dimethylcyclopentene is a cyclic hydrocarbon compound with the molecular formula C7H12. It is a colorless liquid with a strong, pungent odor. The molecule consists of a five-membered carbon ring with two methyl groups attached to adjacent carbon atoms (C3 and C4) and a double bond between C3 and C4. The "cis" configuration indicates that the two methyl groups are on the same side of the double bond. cis-3,4-dimethylcyclopentene is an isomer of trans-3,4-dimethylcyclopentene, which has the methyl groups on opposite sides of the double bond. Cis-3,4-dimethylcyclopentene is used as an intermediate in the synthesis of various organic compounds and can be found in trace amounts in some essential oils.
The CAS Registry Mumber 7459-14-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,5 and 9 respectively; the second part has 2 digits, 1 and 4 respectively. Calculate Digit Verification of CAS Registry Number 7459-14: (6*7)+(5*4)+(4*5)+(3*9)+(2*1)+(1*4)=115 115 % 10 = 5 So 7459-14-5 is a valid CAS Registry Number.
