Check Digit Verification of cas no

The CAS Registry Mumber 188818-73-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,8,1 and 8 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 188818-73:
(8*1)+(7*8)+(6*8)+(5*8)+(4*1)+(3*8)+(2*7)+(1*3)=197
197 % 10 = 7
So 188818-73-7 is a valid CAS Registry Number.

First asymmetric synthesis of the Kelatorphan-like enkephalinase inhibitor (1S,2R,2′S)-2-[2′-(N-hydroxycarbamoylmethyl)-3′- phenylpropionylamino]cyclohexane-1-carboxylic acid

Davies, Stephen G.,Dixon, Darren J.

, p. 2629 - 2634 (2007/10/03)

The first asymmetric synthesis of Kelatorphan-like enkephalinase inhibitor (1S,2R,2′S)-2-[2′-(N-hydroxycarbamoylmethyl)-3′- phenylpropionylamino]cyclohexane-1-carboxylic acid is achieved using lithium amide (R)-5 and pyrrolidinone auxiliary (R)-6; the pyrrolidinone auxiliary is used to create (2S)-benzylsuccinic acid derivative (S)-4 while lithium amide (R)-5 is used to synthesize tert-butyl (1S,2R)-2-aminocyclohexanecarboxylate 3.
