1-Octene, 3,7-dimethyl-, (R)- is a chiral organic compound with the molecular formula C10H20. It is a linear alkene with a double bond between the first and second carbon atoms, and two methyl groups attached to the third and seventh carbon atoms, respectively. The (R)- configuration indicates that the molecule has a specific three-dimensional arrangement, with the higher priority group (based on the Cahn-Ingold-Prelog priority rules) on the right side when looking at the chiral center from the perspective of the double bond. 1-Octene, 3,7-dimethyl-, (R)- is an isomer of 1-octene, 3,7-dimethyl-, (S)-, which has the opposite configuration. It is used in the synthesis of various chemicals and as a building block in organic chemistry.
The CAS Registry Mumber 1117-83-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,1 and 7 respectively; the second part has 2 digits, 8 and 3 respectively. Calculate Digit Verification of CAS Registry Number 1117-83: (6*1)+(5*1)+(4*1)+(3*7)+(2*8)+(1*3)=55 55 % 10 = 5 So 1117-83-5 is a valid CAS Registry Number.
