Check Digit Verification of cas no

The CAS Registry Mumber 502687-12-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,2,6,8 and 7 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 502687-12:
(8*5)+(7*0)+(6*2)+(5*6)+(4*8)+(3*7)+(2*1)+(1*2)=139
139 % 10 = 9
So 502687-12-9 is a valid CAS Registry Number.

New homochiral ketoalcohols from aldol reactions of (+)-isomenthone and reversal of diastereoselectivity

Chughtai, Jameel H.,Gardiner, John M.,Harris, Steven G.,Parsons, Simon,Rankin, David W. H.,Schwalbe, Carl H.

, p. 9043 - 9046 (1997)

Aldol reaction of (+)-isomenthone lithium enolate with aryl and alkyl aldehydes proceeds with complete diastereocontrol at the α-carbon (C6), but the stereochemical outcome at the secondary alcohol stereocentre (established by X-ray crystal structure determinations) can be unexpectedly, reversed by changing reaction quenching temperature. This provides a route to a range of new homochiral ketoalcohols.
