17928-31-3 Usage
General Description
1,7-Dimethoxy octamethyltetrasiloxane is a chemical compound with the formula C12H36O2Si4. It is a colorless liquid with a mild odor, commonly used as a lubricant and as an ingredient in personal care products such as shampoos, conditioners, and moisturizers. It is also used as a surfactant, antifoaming agent, and in the manufacturing of silicone rubbers, resins, and adhesives. The compound is considered to have low toxicity and is generally regarded as safe for use in consumer products when used in accordance with safety guidelines. However, prolonged or excessive exposure to 1,7-Dimethoxy octamethyltetrasiloxane may cause irritation to the skin, eyes, and respiratory system, and caution should be exercised when handling and using products containing this chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 17928-31-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,9,2 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 17928-31:
(7*1)+(6*7)+(5*9)+(4*2)+(3*8)+(2*3)+(1*1)=133
133 % 10 = 3
So 17928-31-3 is a valid CAS Registry Number.

Rate studies of the acid-catalyzed solvolysis of eight-membered cyclosilazoxanes
Lasocki, Zygmunt,Witekowa, Malgorzata
, p. 27 - 33 (2007/10/02)
The solvolysis of N-phenyl-1,1,3,3,5,5,7,7-octamethyl-1,3,5,7-tetrasila-2-aza-4,6,8-trioxacyclooctane (1) and N,N'-diphenyl-1,1,3,3,5,5,7,7-octamethyl-1,3,5,7-tetrasila-2,6-diaza-4,8-dioxacyclooctane (II) in methanol/water in the presence of an acetate buffer is a pseudo-first-order process, subject to general acid-catalysis.The catalytic rate constants have been determined spectrophotometrically for the solvolysis of I.The ring cleavage is slower than that of analogous six-membered cyclosilazoxanes, but the catalytic mode and the solvent isotope effect indicate a close mechanistic similarity between the solvolyses of six- and eight-membered rings.
