Check Digit Verification of cas no

The CAS Registry Mumber 92702-58-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,7,0 and 2 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 92702-58:
(7*9)+(6*2)+(5*7)+(4*0)+(3*2)+(2*5)+(1*8)=134
134 % 10 = 4
So 92702-58-4 is a valid CAS Registry Number.

Atropisomeric amides: Stereoselective enolate chemistry and enantioselective synthesis via a new SmI2-mediated reduction

Hughes, Adam D.,Price, David A.,Simpkins, Nigel S.

, p. 1295 - 1304 (1999)

The use of certain types of atropisomeric amides, incorporating an N-MEM-ortho-tert-bityariume group, for stereoselective reactions, has been explored. Enolate reactions of these systems are highly diastereocontrolled, and enantiomerically enriched starting materials can be obtained, starting from lactic acid, via a new SmI2 mediated reduction process.
