It is a derivative of pregnane, a steroid with a cyclopentane ring fused to a pregnane ring system. The compound features two ethanedithiol (2-mercaptoethyl) groups attached to the 3 and 20 positions of the pregnane core, which contribute to its unique chemical properties. 3,3;20,20-bis-ethanediyldimercapto-5α-pregnane is of interest in the field of organic chemistry and may have potential applications in pharmaceuticals or chemical research due to its structural features and reactivity.
The CAS Registry Mumber 3986-75-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,8 and 6 respectively; the second part has 2 digits, 7 and 5 respectively. Calculate Digit Verification of CAS Registry Number 3986-75: (6*3)+(5*9)+(4*8)+(3*6)+(2*7)+(1*5)=132 132 % 10 = 2 So 3986-75-2 is a valid CAS Registry Number.
