Check Digit Verification of cas no

The CAS Registry Mumber 191470-42-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,4,7 and 0 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 191470-42:
(8*1)+(7*9)+(6*1)+(5*4)+(4*7)+(3*0)+(2*4)+(1*2)=135
135 % 10 = 5
So 191470-42-5 is a valid CAS Registry Number.

Asymmetric synthesis of (+) and (-) trans-2,6-dimethylpiperidines

Freville, Stephanie,Bonin, Martine,Celerier, Jean-Peirre,Husson, Henri-Philippe,Lhommet, Gerard,Quirion, Jean-Charles,Thuy, Vu Moc

, p. 8447 - 8456 (2007/10/03)

(+) aid (-) trans-2,6-dimethylpiperidines 9 have been prepared from diastereomeric lactams 6 and 11, both available from (R)-(-)-phenylglycinol 4. Diastereoselective C-2 alkylation afforded oxazolidines 7 and 12. Reduction of 7 with LiAlH4 or NaBH4 led to trans-2,6-8 with total retention of configuration. When 12 was reduced with NaBH4, trans derivative 13a was isolated as the major isomer. A mechanism is proposed to explain the different results.
