Check Digit Verification of cas no

The CAS Registry Mumber 139345-74-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,3,4 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 139345-74:
(8*1)+(7*3)+(6*9)+(5*3)+(4*4)+(3*5)+(2*7)+(1*4)=147
147 % 10 = 7
So 139345-74-7 is a valid CAS Registry Number.

Ligand-assisted asymmetric synthesis. I. Modelling of chiral auxiliaries for the diastereoselective Diels-Alder reaction

Gras,Pellissier

, p. 7043 - 7046 (2007/10/02)

The chiral auxiliaries derived from threitol are particularly well designed to form chelated complexes with Lewis acids. The diastereoselective Diels-Alder addition to cyclopentadiene is the consequence of a roof shaped semirigid conformation, as demonstr
