Check Digit Verification of cas no

The CAS Registry Mumber 178419-46-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,8,4,1 and 9 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 178419-46:
(8*1)+(7*7)+(6*8)+(5*4)+(4*1)+(3*9)+(2*4)+(1*6)=170
170 % 10 = 0
So 178419-46-0 is a valid CAS Registry Number.

A chiral synthesis of (-)-spiro[1-azabicyclo[2.2.2]octane-3,5′- oxazolidin-2′-one]: A conformationally restricted analogue of acetylcholine that is a potent and selective α7 nicotinic receptor agonist

Macor, John E.,Mullen, George,Verhoest, Patrick,Sampognaro, Anthony,Shepardson, Bruce,Mack, Robert A.

, p. 6493 - 6495 (2004)

A direct, short chiral synthesis of the selective α7 nicotinic receptor agonist (-)-spiro[1-azabicyclo[2.2.2]-octane-3,5′-oxazolidin- 2′-one] (AR-R17779) is presented. The key step utilized attack of the dianion of the (R)-HYTRA ester [(R)-(+)-2-hydroxy-1,2,2-triphenylethyl acetate] on quinuclidin-3-one, followed by a selective precipitation of the diasteriomeric tertiary alcohol that led to (S)-(-)-AR-R17779 in two additional steps.
