The molecule features a heptamethyl group, which consists of seven methyl groups (CH3), attached to the cyclotetrasiloxane ring. Additionally, it has an acetic acid functional group (-COOH) attached to the ring, making it an interesting compound for various applications in the fields of polymer chemistry, material science, and pharmaceuticals. Its unique structure and properties make it a potential candidate for the development of new materials with specific characteristics, such as thermal stability, low toxicity, and high biocompatibility.
The CAS Registry Mumber 3244-43-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,4 and 4 respectively; the second part has 2 digits, 4 and 3 respectively. Calculate Digit Verification of CAS Registry Number 3244-43: (6*3)+(5*2)+(4*4)+(3*4)+(2*4)+(1*3)=67 67 % 10 = 7 So 3244-43-7 is a valid CAS Registry Number.
