It is a derivative of the naphthalenone class, characterized by the presence of a naphthalene ring system with a ketone functional group. This specific compound features a methyl group at the 2-position, and three methoxy groups attached at the 5, 7, and 8 positions, respectively. The 3,4-dihydro part of its name indicates that the molecule has two hydrogen atoms added to the 3 and 4 positions of the naphthalene ring, which reduces the ring's unsaturation and makes it more stable. 5,7,8-trimethoxy-2-methyl-3,4-dihydro-2H-naphthalen-1-one is known for its potential applications in the synthesis of various pharmaceuticals and natural products due to its unique structure and reactivity.
The CAS Registry Mumber 1702-71-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,0 and 2 respectively; the second part has 2 digits, 7 and 1 respectively. Calculate Digit Verification of CAS Registry Number 1702-71: (6*1)+(5*7)+(4*0)+(3*2)+(2*7)+(1*1)=62 62 % 10 = 2 So 1702-71-2 is a valid CAS Registry Number.
