Check Digit Verification of cas no

The CAS Registry Mumber 221885-20-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,8,8 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 221885-20:
(8*2)+(7*2)+(6*1)+(5*8)+(4*8)+(3*5)+(2*2)+(1*0)=127
127 % 10 = 7
So 221885-20-7 is a valid CAS Registry Number.

Diastereo- and enantioselective formal synthesis of (+)-conagenin via asymmetric [2,3]-Wittig rearrangement

Enders, Dieter,Bartsch, Michael,Runsink, Jan

, p. 243 - 248 (1999)

The formal synthesis of the immunomodulator (+)-conagenin (1) is accomplished in a twelve-step sequence with good overall yield (19%), diastereoselectivity and enantiomeric excess (ds(syn) = 88%, ee = 91%). Key steps of the synthesis are the asymmetric [2
