Polyethylhydrosiloxane (PEHMS), also known as PEHMS, is a silicone compound that is widely used as a coating agent and release agent in various industrial applications. It is a clear, odorless, and non-toxic liquid that is highly resistant to oxidation and thermal degradation. PEHMS exhibits excellent water repellency, low surface tension, and great adhesion properties, making it an ideal choice for waterproofing and anti-stick coatings. It is also commonly used in the production of personal care products, such as cosmetics and skin care formulations, due to its ability to provide a smooth and silky texture to the end products. Overall, Polyethylhydrosiloxane is a versatile and effective chemical with a broad range of applications across different industries.

Check Digit Verification of cas no

The CAS Registry Mumber 24979-95-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,9,7 and 9 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 24979-95:
(7*2)+(6*4)+(5*9)+(4*7)+(3*9)+(2*9)+(1*5)=161
161 % 10 = 1
So 24979-95-1 is a valid CAS Registry Number.
