Check Digit Verification of cas no
The CAS Registry Mumber 57819-19-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,8,1 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 57819-19:
(7*5)+(6*7)+(5*8)+(4*1)+(3*9)+(2*1)+(1*9)=159
159 % 10 = 9
So 57819-19-9 is a valid CAS Registry Number.

The rearrangement of 5-cholestene to (20ξ)-13(17)-diacholestenes, separation of C-20 epimers, and further reduction provided an unambiguous synthesis of the biomarkers (20R)- and (20S)-13β,17α(H)-diacholestanes.Repetition of this sequence using (24R)-5-campestene or (24R)-5-stigmastene provided the analogous C28 and C29 diasteranes.
