6569-34-2

The term "dihydro-" is a prefix used in chemistry to denote the presence of two hydrogen atoms in a compound. It is often found in the names of hydrocarbons and their derivatives, where it indicates a reduction in the number of hydrogen atoms compared to the parent compound. For instance, dihydroxybenzene has two fewer hydrogen atoms than benzene, which has three hydroxyl groups attached. This prefix is not only limited to hydrocarbons but can also be applied to other chemical classes, such as dihydrogen monoxide, which is another name for water (H2O). The "dihydro-" prefix is a useful tool in chemical nomenclature for describing the composition and structure of molecules.

6569-34-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6569-34-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,6 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 6569-34:
(6*6)+(5*5)+(4*6)+(3*9)+(2*3)+(1*4)=122
122 % 10 = 2
So 6569-34-2 is a valid CAS Registry Number.

, p. 1123 - 1130 (2008/02/08)

Direct reaction of propan-1,3-diselenol with thiophene-2-carbaldehydes in trimethylchlorosilane medium is studied. Synthetic procedure for preparation of the previously unknown 1,3-diselenanes of thiophene series is developed. Structure of the newly obtained compounds is established by 1H, 13C, and 77Se NMR spectroscopy. Chromatomass spectrometric stidy of the products obtained is carried out. In some cases reaction may be directed to the synthetis of new types of polymers of original structure. Pleiades Publishing, Inc., 2006.
