Check Digit Verification of cas no

The CAS Registry Mumber 181872-32-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,8,7 and 2 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 181872-32:
(8*1)+(7*8)+(6*1)+(5*8)+(4*7)+(3*2)+(2*3)+(1*2)=152
152 % 10 = 2
So 181872-32-2 is a valid CAS Registry Number.

Asymmetric synthesis. 39. Synthesis of 2-(1-aminoalkyl)piperidines via 2-cyano-6-phenyl oxazolopiperidine

Froelich, Olivier,Desos, Patrice,Bonin, Martine,Quirion, Jean-Charles,Husson, Henri-Philippe,Zhu, Jieping

, p. 6700 - 6705 (2007/10/03)

The asymmetric synthesis of a series of 2-(1-aminoalkyl) piperidines using (-)-2-cyano-6-phenyloxazolopiperidine 1 is described. LiAlH4 reduction of 1 followed by hydrogenolysis led to the diamine 3. The same strategy applied to C-2-methylated
