Check Digit Verification of cas no

The CAS Registry Mumber 186045-40-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,6,0,4 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 186045-40:
(8*1)+(7*8)+(6*6)+(5*0)+(4*4)+(3*5)+(2*4)+(1*0)=139
139 % 10 = 9
So 186045-40-9 is a valid CAS Registry Number.

Lewis acid-promoted asymmetric conjugate allylation of N-acyl-2,3-dihydro-4-pyridones induced by intramolecular π interactions

Sato, Masayuki,Aoyagi, Sakae,Yago, Seiji,Kibayashi, Chihiro

, p. 9063 - 9066 (1996)

Lewis acid-promoted conjugate addition reaction of an allylsilane to a series of the chiral 8-arylmenthol-derived N-acyl-2,3-dihydro-4-pyridones leads to the 2-allyl-4-piperidones with moderate to high levels of asymmetric induction, indicating π-stacking contribution to chirality control. This methodology was applied to the asymmetric synthesis of (-)-N-methylconiine. Copyright (C) 1996 Elsevier Science Ltd.
