Check Digit Verification of cas no

The CAS Registry Mumber 115147-98-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,1,4 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 115147-98:
(8*1)+(7*1)+(6*5)+(5*1)+(4*4)+(3*7)+(2*9)+(1*8)=113
113 % 10 = 3
So 115147-98-3 is a valid CAS Registry Number.

SYNTHESIS OF MACROCYCLIC ACETALS CONTAINING LIPOPHILIC SUBSTITUENTS

Bradshaw, Jerald S.,Krakowiak, Krzysztof E.,LindH, Gypzy C.,Izatt, Reed M.

, p. 4271 - 4276 (2007/10/02)

A series of new mecrocyclic acetals all containing lipophilic substituents were prepared by reacting the appropriate diols and lipophilic acetal-containing dichlorides or ditosylates.The reactions using the ditosylates gave the best yields.Several of the macrocycles contained pyridine subcyclic units.The lipophilic acetals were obtained by reacting a chain aldehyde with 2-hydroxyethyl chloride or tosylate and 3-hydroxypropyl chloride od tosylate.At least two of the new pydridino ligands complexed with metal ions as shown by the use of these materials as carriers for silver nitrate through a water-methylene chloride-water bulk liquid membrane system.
