Check Digit Verification of cas no

The CAS Registry Mumber 676472-07-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,6,4,7 and 2 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 676472-07:
(8*6)+(7*7)+(6*6)+(5*4)+(4*7)+(3*2)+(2*0)+(1*7)=194
194 % 10 = 4
So 676472-07-4 is a valid CAS Registry Number.

Synthesis and complexing properties of crownophanes possessing carboxyl group

Inokuma, Seiichi,Funaki, Takashi,Hara, Daisuke,Nishimura, Jun

, p. 333 - 346 (2007/10/03)

A new series of crown compounds bearing two carboxyl groups (2a-c; crownophanedicarboxylic acids) were prepared via intramolecular [2 + 2] photocycloaddition of bis-styrene derivatives. In the liquid-liquid extraction, crownophanedicarboxylic acids (2a-c) showed a low affinity toward alkali metal cations, though both 2b and 2c showed an extraordinary high affinity toward zinc cation among heavy metal cations examined.
