Check Digit Verification of cas no

The CAS Registry Mumber 1421636-94-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,6,3 and 6 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1421636-94:
(9*1)+(8*4)+(7*2)+(6*1)+(5*6)+(4*3)+(3*6)+(2*9)+(1*4)=143
143 % 10 = 3
So 1421636-94-3 is a valid CAS Registry Number.

C-alkylation of chiral tropane- and homotropane-derived enamines

Hodgson, David M.,Charlton, Andrew,Paton, Robert S.,Thompson, Amber L.

, p. 1508 - 1518 (2013)

The synthesis and alkylation of chiral, nonracemic tropane- and homotropane-derived enamines is examined as an approach to enantioenriched α-alkylated aldehydes. The two bicyclic N auxiliaries, which differ by a single methylene group, give opposite senses of asymmetric induction on alkylation with EtI and provide modestly enantioenriched 2-ethylhexanal (following hydrolysis of the alkylated iminium). The observed stereoselectivity is supported by density functional studies of ethylation for both enamines.
