The chemical compound "(C2H5)3SnOC(C6H5)(CF3)CH2COCH3" is a complex organotin compound with a molecular formula of C21H31F3O2Sn. It consists of a central tin (Sn) atom bonded to three ethyl groups (C2H5), an oxygen atom, and a phenyl group (C6H5) with a trifluoromethyl group (CF3) attached to it. The phenyl group is further connected to a methylene group (CH2), which is bonded to a carbonyl group (CO) and an ethyl group (CH3). (C2H5)3SnOC(C6H5)(CF3)CH2COCH3 is characterized by its unique structure, which combines the properties of organotin compounds with those of aromatic and fluorinated groups, potentially leading to specific applications in areas such as catalysis, polymer chemistry, or as a precursor in the synthesis of more complex molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 17981-18-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,9,8 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 17981-18:
(7*1)+(6*7)+(5*9)+(4*8)+(3*1)+(2*1)+(1*8)=139
139 % 10 = 9
So 17981-18-9 is a valid CAS Registry Number.
