TDS/TCS returns will not be accepted if TAN is not quoted and challans for TDS/TCS payments will not be accepted by banks. Failure to apply for TAN or not quoting the same in the specified documents attracts a penalty of ₹10,000 No documents are required to be filed with the application for allotment of TAN.
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.
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.
The mechanism begins by generation of Si(CH 3) 3 X and a highly reactive [CF 3] − (trifluoromethide) intermediate. The [CF 3 ] − attacks the carbonyl to generate an alkoxide anion. The alkoxide is silylated by the reagent to give the overall addition product, plus [CF 3 ] − , thus propagating an anionic chain reaction.
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.
Trichloroethyl chloroformate is used in organic synthesis for the introduction of the trichloroethyl chloroformate (Troc) protecting group for amines, thiols and alcohols.It readily cleaves vs other carbamates and can be used in an overall protecting group strategy.
