Check Digit Verification of cas no

The CAS Registry Mumber 140160-62-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,1,6 and 0 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 140160-62:
(8*1)+(7*4)+(6*0)+(5*1)+(4*6)+(3*0)+(2*6)+(1*2)=79
79 % 10 = 9
So 140160-62-9 is a valid CAS Registry Number.

Asymmetric Diels-Alder Cycloadditions with Chiral Carbamoyl Dienophiles

Defoin, Albert,Brouillard-Poichet, Agnes,Streith, Jacques

, p. 109 - 123 (2007/10/02)

Chiral acylnitroso dienophiles 14, which were obtained from L-proline and from D-mandelic acid, reacted with cyclohexa-1,3-diene to give the expected diastereoisomers 15 and 16 (Scheme 2 and Table 1).The d.e. values for these Diels-Alder reactions were moderate; they are related to the molecular stiffness of the dienophiles.The absolute configuration of the major cycloadducts was interpreted in terms of HOMO/LUMO interactions, the approach being 'endo' and the acylnitroso dienophiles reacting from their s-cis-conformation.
