Check Digit Verification of cas no
The CAS Registry Mumber 27628-47-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,6,2 and 8 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 27628-47:
(7*2)+(6*7)+(5*6)+(4*2)+(3*8)+(2*4)+(1*7)=133
133 % 10 = 3

Synthesis of 2,3-Dihydro-1H-pyrrolizine-7-carbaldehyde, the Sex Pheromone Danaidal
Roeder, Erhard,Wiedenfeld, Helmut,Bourauel, Thomas
, p. 1645 - 1647 (2007/10/02)
Danaidal (4) can easily be obtained in high yields from ethyl 2,3,5,6-tetrahydro-1H-pyrrolizine-7-carboxylate (1) via sulphur dehydrogenation or MnO2 oxidation, subsequent reduction to dehydrosupinidine (3), and further oxidation to the desired title compound 4.
