It is also known for its ability to enhance the spreadability and absorption of active ingredients in skincare products. Additionally, CETETH-10 is considered safe for use in cosmetics and has low skin irritation potential. Overall, it is a versatile ingredient that is commonly found in a wide range of skincare products.
Check Digit Verification of cas no
The CAS Registry Mumber 14529-40-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,5,2 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 14529-40:
(7*1)+(6*4)+(5*5)+(4*2)+(3*9)+(2*4)+(1*0)=99
99 % 10 = 9
So 14529-40-9 is a valid CAS Registry Number.

Combinatorial synthesis of PEG oligomer libraries

Page/Page column 10, (2010/02/15)
A simple chain-extending approach was established for the scale-up of the monoprotected monodisperse PEG diol materials. Reactions of THP-(OCH2CH2)n—OMs (n=4, 8, 12) with a large excess of commercially available H—(OCH2CH2)n—OH (n=1-4) under basic conditions led to THP-(OCH2CH2)n—OH (n=5-15). Similarly, Me-(OCH2CH2)n—OH (n=4-11, 13) were prepared from Me-(OCH2CH2)n—OMs (n=3, 7, 11). For the chain elongation steps, 40-80% yields were achieved through extraction purification. PEG oligomer libraries I and II were generated in 50-95% overall yields by alkylation or acylation of THP-(OCH2CH2)n—OH (n=1-15) followed by deprotection. Alkylation of Me-(OCH2CH2)n—OH (n=1-11, 13) with X—(CH2)m—CO2R (X=Br or OMs) and subsequent hydrolysis led to PEG oligomer library III in 30-60% overall yields. Combinatorial purification techniques were adapted to the larger-scale library synthesis. A total of 498 compounds, each with a weight of 2-5 g and a minimum purity of 90%, were synthesized.
