(1R)-trans-1,2-dimethyl-cyclopropane is a cyclic alkane with a unique structure, consisting of three carbon atoms forming a closed ring and two methyl groups attached to adjacent carbons. This organic compound is characterized by its trans configuration, meaning that the methyl groups are positioned on opposite sides of the ring. The chiral center at the first carbon atom (C1) gives rise to two enantiomers, with the (1R)-enantiomer being the specific isomer in question. (1R)-trans-1,2-dimethyl-cyclopropane is of interest in organic chemistry due to its strained ring structure, which can lead to unique chemical reactivity and properties. It is also a valuable precursor in the synthesis of various pharmaceuticals and agrochemicals, as well as a model compound for studying the effects of ring strain on chemical behavior.

Check Digit Verification of cas no

The CAS Registry Mumber 20520-64-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,5,2 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 20520-64:
(7*2)+(6*0)+(5*5)+(4*2)+(3*0)+(2*6)+(1*4)=63
63 % 10 = 3
So 20520-64-3 is a valid CAS Registry Number.
