Check Digit Verification of cas no

The CAS Registry Mumber 119580-48-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,5,8 and 0 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 119580-48:
(8*1)+(7*1)+(6*9)+(5*5)+(4*8)+(3*0)+(2*4)+(1*8)=142
142 % 10 = 2
So 119580-48-2 is a valid CAS Registry Number.

Macroheterocycles. 34. Synthesis and Enantiomeric Selectivity of Chiral Azacrown

Luk'yanenko, N. G.,Lobach, A. V.,Nazarova, N. Yu.,Karpenko, L. P.,Lyamtseva, L. N.

, p. 562 - 566 (1988)

Chiral azacrown ethers were obtained by the condensation of (4S,5S)-4,5-ditosyloxymethyl-2,2-dimethyl-1,3-dioxolane with 6-benzyl-3,9-dioxa-6-azaundecane-1,11-diol.Their debenzylation and deacetalization were realized.The enantiomeric selectivity in the complex formation between the obtained crown ethers and the hydrochlorides of L- and D-valine methyl esters was determined by a potentiometric method.The chiral azacrown ethers exhibit higher enantioselectivity than their oxygen analogs.
