Check Digit Verification of cas no
The CAS Registry Mumber 64520-57-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,5,2 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 64520-57:
(7*6)+(6*4)+(5*5)+(4*2)+(3*0)+(2*5)+(1*7)=116
116 % 10 = 6
So 64520-57-6 is a valid CAS Registry Number.

Stereoselective synthesis of a new trihydroxyindolizidine lactone
Pisaneschi, Federica,Piacenti, Michela,Cordero, Franca M.,Brandi, Alberto
, p. 292 - 296 (2006)
A general approach to 1,6,7-trihydroxyindolizidin-8-carboxylates is illustrated through the synthesis of a γ-lactone in an enantiopure form in seven steps starting from (3S)-3-t-butyloxy-1-pyrroline N-oxide and the acetonide of (2E,4S)-4,5-dihydroxy-2-pentenoic acid derived from (S)-malic acid and mannitol, respectively. The process was completely stereoselective and allowed the total control of the relative and absolute configuration of the five contiguous stereocentres of the product.
