Description
1,11-Dihydroxy dodecamethyl hexasiloxane, also known as cyclomethicone 5, is a silicone-based organic compound that is widely used in personal care products and cosmetics. It is a clear, odorless liquid that functions as a skin conditioning agent, emollient, and solvent. This chemical helps to improve the spreadability and consistency of products, providing a smooth and silky texture to creams, lotions, and hair care formulations. It is also known for its ability to enhance the skin's moisture-retaining properties, making it a popular ingredient in moisturizers and other hydrating products. Additionally, 1,11-Dihydroxy dodecamethyl hexasiloxane is considered to be safe for use in cosmetics and personal care products, as it does not pose any known health risks when properly formulated and used in accordance with industry guidelines.

Check Digit Verification of cas no
The CAS Registry Mumber 4029-00-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,2 and 9 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4029-00:
(6*4)+(5*0)+(4*2)+(3*9)+(2*0)+(1*0)=59
59 % 10 = 9
So 4029-00-9 is a valid CAS Registry Number.

Hydrogenolysis of Polysilanes Catalyzed by Low-Valent Nickel Complexes

The dehydrogenation of organosilanes (RxSiH4?x) under the formation of Si?Si bonds is an intensively investigated process leading to oligo- or polysilanes. The reverse reaction is little studied. To date, the hydrogenolysis of Si?Si bonds requires very harsh conditions and is very unselective, leading to multiple side products. Herein, we describe a new catalytic hydrogenation of oligo- and polysilanes that is highly selective and proceeds under mild conditions. New low-valent nickel hydride complexes are used as catalysts and secondary silanes, RR′SiH2, are obtained as products in high purity.
