2,2-Dichloro-5α-cholestan-3-one is a chemical compound with the molecular formula C27H44Cl2O. It is a derivative of cholestan-3-one, a steroid ketone, where two chlorine atoms are attached to the 2-position of the steroid nucleus. 2,2-dichloro-5α-cholestan-3-one is characterized by its unique structure, which includes a cyclohexane ring fused to a cyclopentane ring, with a ketone group at the 3-position and two chlorine atoms at the 2-position. It is often used in the synthesis of various steroidal compounds and has potential applications in the pharmaceutical industry due to its structural similarity to natural steroids. The compound's properties, such as solubility and reactivity, can be influenced by the presence of the chlorine atoms, making it a valuable intermediate in organic synthesis.

Check Digit Verification of cas no

The CAS Registry Mumber 2239-52-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,3 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2239-52:
(6*2)+(5*2)+(4*3)+(3*9)+(2*5)+(1*2)=73
73 % 10 = 3
So 2239-52-3 is a valid CAS Registry Number.
