Check Digit Verification of cas no

The CAS Registry Mumber 1207519-35-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,7,5,1 and 9 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1207519-35:
(9*1)+(8*2)+(7*0)+(6*7)+(5*5)+(4*1)+(3*9)+(2*3)+(1*5)=134
134 % 10 = 4
So 1207519-35-4 is a valid CAS Registry Number.

Calix[4]arene-dithiacrown ethers: synthesis and potentiometric membrane sensing of Hg2+

Yang, Yanfei,Cao, Xiaodan,Surowiec, Malgorzata,Bartsch, Richard A.

experimental part, p. 447 - 454 (2010/03/03)

A series of calix[4]arene-dithiacrown-5 and -dithiacrown-6 compounds in cone and 1,3-alternate conformations has been synthesized. Responses of these ionophores to Hg2+ and competing metal ions were determined in solvent polymeric membrane electrodes. High potentiometric selectivity for Hg2+ over Na+ and a variety of transition and heavy metal ions was obtained.
