Trimethylsilane is the organosilicon compound with the formula (CH 3) 3 SiH. It is a trialkylsilane. The Si-H bond is reactive. Being a gas, it is less commonly used as a reagent than the related triethylsilane, which is a liquid at room temperature.
No TDS shall be deducted if the single-time payment to the contractor does not exceed RS. 35000 or Rs. 1,00,000 in aggregate during the year. TDS Can be deducted when the date of actual payment of cash or the date of crediting the sum to the payee's account or the date of issue of cheque, draft, or by any other mode, whichever is earlier.

Triethyl orthoformate is an organic compound with the formula HC(OC 2 H 5) 3. This colorless volatile liquid, the ortho ester of formic acid , is commercially available. The industrial synthesis is from hydrogen cyanide and ethanol.
The check digit is found by taking the last digit times 1, the preceding digit times 2, the preceding digit times 3 etc., adding all these up and computing the sum modulo 10. For example, the CAS number of water is 7732-18-5: the checksum 5 is calculated as (8×1 + 1×2 + 2×3 + 3×4 + 7×5 + 7×6) = 105; 105 mod 10 = 5.
2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) is a polychlorinated dibenzo-p-dioxin (sometimes shortened, though inaccurately, to simply 'dioxin') [3] with the chemical formula C 12 H 4 Cl 4 O 2. Pure TCDD is a colorless solid with no distinguishable odor at room temperature.
1-Ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC, EDAC or EDCI) is a water-soluble carbodiimide usually handled as the hydrochloride. [1] It is typically employed in the 4.0-6.0 pH range. It is generally used as a carboxyl activating agent for the coupling of primary amines to yield amide bonds.
