4,4-Dimethyl-cholestadien-(2,5) is a steroidal compound characterized by the presence of two methyl groups at the 4th carbon position and a double bond between the 2nd and 5th carbon atoms. It is derived from the cholesterol molecule, which is a key component in the synthesis of various hormones and bile acids in the human body. 4,4-Dimethyl-cholestadien-(2,5) is of interest in the field of organic chemistry and biochemistry, particularly in the study of steroidal structures and their potential applications in pharmaceuticals and other industries. Its unique structure allows for further functionalization and modification, making it a valuable intermediate in the synthesis of more complex steroidal compounds.
The CAS Registry Mumber 4118-68-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,1 and 8 respectively; the second part has 2 digits, 6 and 8 respectively. Calculate Digit Verification of CAS Registry Number 4118-68: (6*4)+(5*1)+(4*1)+(3*8)+(2*6)+(1*8)=77 77 % 10 = 7 So 4118-68-7 is a valid CAS Registry Number.
