Check Digit Verification of cas no
The CAS Registry Mumber 1551-08-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,5 and 1 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1551-08:
(6*1)+(5*5)+(4*5)+(3*1)+(2*0)+(1*8)=62
62 % 10 = 2
So 1551-08-2 is a valid CAS Registry Number.

Hydrogenation of pyrrolizin-3-ones; New routes to pyrrolizidines
Despinoy, Xavier L. M.,McNab, Hamish
experimental part, p. 4502 - 4511 (2009/12/25)
Pyrrolizin-3-ones (e.g.1) can be easily hydrogenated to their hexahydro (pyrrolizidin-3-one) derivatives in the presence of heterogeneous catalysts. Good diastereoselectivity (up to >97:3, depending on catalysts and solvent) can be achieved if the pyrroli
