Its chiral centers at positions 3a, 4, 5, and 6a contribute to its stereochemistry, making it a potential candidate for applications in the pharmaceutical or chemical industries where stereoselectivity is important.
The CAS Registry Mumber 39968-91-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,9,6 and 8 respectively; the second part has 2 digits, 9 and 1 respectively. Calculate Digit Verification of CAS Registry Number 39968-91: (7*3)+(6*9)+(5*9)+(4*6)+(3*8)+(2*9)+(1*1)=187 187 % 10 = 7 So 39968-91-7 is a valid CAS Registry Number.
