4-methylsulfanyl-1,2-diphenyl-5,6,7,8-tetrahydro-quinazolinium; iodide is a complex organic compound with the chemical formula C18H20N2S+I-. It is a derivative of quinazolinium, a heterocyclic compound with a fused benzene ring and a quinazoline ring. The molecule features a methylsulfanyl group (-SCH3) at the 4-position, two phenyl rings at the 1 and 2 positions, and a tetrahydro structure, indicating the presence of four hydrogen atoms in the ring. The compound is a salt, with the iodide ion (I-) as the counterion. It is likely to be used in chemical research or as an intermediate in the synthesis of other compounds, given its structural complexity and the presence of multiple functional groups.
The CAS Registry Mumber 5185-17-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,8 and 5 respectively; the second part has 2 digits, 1 and 7 respectively. Calculate Digit Verification of CAS Registry Number 5185-17: (6*5)+(5*1)+(4*8)+(3*5)+(2*1)+(1*7)=91 91 % 10 = 1 So 5185-17-1 is a valid CAS Registry Number.
