78646-19-2

(1S,4S,9R)-2,9-Dimethyl-1,3-diphenyl-1,4-dihydro-1,4-methano-naphthalene is a complex organic compound with a unique molecular structure. It is characterized by its chiral centers at the 1st, 4th, and 9th carbon atoms, which are in the S, S, and R configurations, respectively. The compound features two methyl groups at the 2nd and 9th positions, and two phenyl rings attached to the 1st and 3rd carbons. The presence of a dihydro-1,4-methano-naphthalene ring system indicates that it has a partially saturated naphthalene structure with a bridgehead carbon atom connecting the two aromatic rings. This specific arrangement of atoms and functional groups gives the compound its distinct chemical properties and potential applications in various fields, such as pharmaceuticals, materials science, and organic chemistry research.

78646-19-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 78646-19-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,6,4 and 6 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 78646-19:
(7*7)+(6*8)+(5*6)+(4*4)+(3*6)+(2*1)+(1*9)=172
172 % 10 = 2
So 78646-19-2 is a valid CAS Registry Number.
