Check Digit Verification of cas no

The CAS Registry Mumber 259249-36-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,9,2,4 and 9 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 259249-36:
(8*2)+(7*5)+(6*9)+(5*2)+(4*4)+(3*9)+(2*3)+(1*6)=170
170 % 10 = 0
So 259249-36-0 is a valid CAS Registry Number.

Enantioselective syntheses of ent-sedridine and (+)-coniine via proline-catalyzed mannich reaction

Nagata, Kazuhiro,Nishimura, Kosuke,Yokoya, Masashi,Itoh, Takashi

, p. 335 - 344 (2007/10/03)

Proline-catalyzed three component Mannich reaction using 5-hydroxypentanal as a substrate was achieved in high enantioselectivity to construct a chiral center at C-2 position of 2-substituted piperidine alkaloids. The method was applied to the total syntheses of ent-sedridine and (+)-coniine.
