The term "3-cyclopropyl-" refers to a chemical structure where a cyclopropyl group, which is a three-carbon ring, is attached to a molecule at the third position. Cyclopropyl groups are known for their unique properties due to the ring strain caused by the small size of the three-membered ring. This structural feature can significantly influence the reactivity, stability, and physical properties of the compound it is part of. In pharmaceuticals and organic chemistry, 3-cyclopropyl-substituted compounds can exhibit distinct biological activities and chemical behaviors, making them important in the design of drugs and other chemical products. The cyclopropyl group's small size and ring strain can lead to increased reactivity and unique conformational effects, which are valuable in various chemical and biological applications.
The CAS Registry Mumber 4364-55-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,6 and 4 respectively; the second part has 2 digits, 5 and 5 respectively. Calculate Digit Verification of CAS Registry Number 4364-55: (6*4)+(5*3)+(4*6)+(3*4)+(2*5)+(1*5)=90 90 % 10 = 0 So 4364-55-0 is a valid CAS Registry Number.
