Check Digit Verification of cas no

The CAS Registry Mumber 118173-33-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,1,7 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 118173-33:
(8*1)+(7*1)+(6*8)+(5*1)+(4*7)+(3*3)+(2*3)+(1*3)=114
114 % 10 = 4
So 118173-33-4 is a valid CAS Registry Number.

Azapropellanes 5. Synthesis of chiral (non-racemic) 2-methyl azapropellanes

McIntosh, John M.,Acquaah, Samual O.

, p. 1752 - 1756 (2007/10/02)

The preparation of S-(-)-6-methyl-2-piperidinone from S-alanine and R-(-)-5-methyl-2-pyrrolidinone from S-glutamic acid and their conversion into S-2-methyl-1-azoniatricyclo1.6>tetradecane (2a) and R-2-methyl-1-azoniatricyclo1.6>tridecane (2b) with enantiomeric excesses of 95 and 92percent respectively are described.The use of these compounds as phase-transfer catalysts did not lead to significant asymmetric induction.
