The chemical "5-(3-benzyloxy-benzyl)-6-methyl-7,8-dihydro-[1,3]dioxolo[4,5-g]isoquinolinium; iodide" is a complex organic compound with the molecular formula C26H24NO3+ and the iodide anion (I-) as its counterion. It features a benzyloxy-benzyl group attached to the 5-position of a 6-methyl-7,8-dihydro-[1,3]dioxolo[4,5-g]isoquinolinium core. The presence of the dihydro-[1,3]dioxolo[4,5-g]isoquinolinium ring system indicates a fused ring structure with a dioxolane ring and an isoquinolinium ring. 5-(3-benzyloxy-benzyl)-6-methyl-7,8-dihydro-[1,3]dioxolo[4,5-g]isoquinolinium; iodide is likely to be used in the synthesis of pharmaceuticals or as an intermediate in organic chemistry due to its unique structure and potential reactivity.
The CAS Registry Mumber 1980-12-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,8 and 0 respectively; the second part has 2 digits, 1 and 2 respectively. Calculate Digit Verification of CAS Registry Number 1980-12: (6*1)+(5*9)+(4*8)+(3*0)+(2*1)+(1*2)=87 87 % 10 = 7 So 1980-12-7 is a valid CAS Registry Number.
