Triethyl-(1-methyl-prop-2-ynyloxy)-stannane, also known as 1-methyl-3-(triethylstannyl)prop-2-yn-1-ol, is an organotin compound characterized by a tin atom bonded to three ethyl groups and a 1-methyl-prop-2-ynyloxy group. triethyl-(1-methyl-prop-2-ynyloxy)-stannane is primarily used as a reagent in organic synthesis, particularly in the formation of carbon-carbon bonds through the Stille coupling reaction, a widely employed cross-coupling method in organic chemistry. The 1-methyl-prop-2-ynyloxy group in triethyl-(1-methyl-prop-2-ynyloxy)-stannane acts as a protecting group for the alkynyl moiety, allowing for selective reactions at the tin center. Triethyl-(1-methyl-prop-2-ynyloxy)-stannane is a colorless liquid with a relatively low melting point and is sensitive to air and moisture, necessitating careful handling and storage under an inert atmosphere.

Check Digit Verification of cas no

The CAS Registry Mumber 1067-35-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,6 and 7 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1067-35:
(6*1)+(5*0)+(4*6)+(3*7)+(2*3)+(1*5)=62
62 % 10 = 2
So 1067-35-2 is a valid CAS Registry Number.
