18772-36-6 Usage
General Description
Eicosamethylcyclopentasiloxane is a type of silicone-based compound commonly used in cosmetic and personal care products. It is a cyclic siloxane compound with a molecular formula of C26H54O6Si6. This chemical is known for its ability to provide a smooth and silky feel to skin and hair, and it is often used as an emollient and conditioning agent in various beauty products such as lotions, creams, and hair care products. Eicosamethylcyclopentasiloxane has a low viscosity and evaporates quickly, which allows it to spread easily and provide a non-greasy, smooth texture. It is considered safe for use in cosmetics and personal care products, and it is often used as an alternative to traditional hydrocarbon-based oils and emollients.
Check Digit Verification of cas no
The CAS Registry Mumber 18772-36-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,7,7 and 2 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 18772-36:
(7*1)+(6*8)+(5*7)+(4*7)+(3*2)+(2*3)+(1*6)=136
136 % 10 = 6
So 18772-36-6 is a valid CAS Registry Number.

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.
