Tert-butyl 2-thienyl sulfoxide is an organic compound with the chemical formula C9H14OS. It is a derivative of thiophene, a heterocyclic compound consisting of a benzene ring with one sulfur atom replacing one carbon atom. The tert-butyl group (C4H9) is attached to the sulfur atom, making it a sulfoxide, which is an intermediate oxidation state between sulfide and sulfone. tert-butyl 2-thienyl sulfoxide is known for its potential applications in the synthesis of various organic compounds, particularly in the pharmaceutical and agrochemical industries, due to its unique reactivity and stability. It is also used as a precursor in the preparation of other sulfur-containing compounds. Tert-butyl 2-thienyl sulfoxide is a colorless to pale yellow liquid with a characteristic odor and is sensitive to light and air, requiring storage under an inert atmosphere.

Check Digit Verification of cas no

The CAS Registry Mumber 3751-70-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,5 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3751-70:
(6*3)+(5*7)+(4*5)+(3*1)+(2*7)+(1*0)=90
90 % 10 = 0
So 3751-70-0 is a valid CAS Registry Number.
