Check Digit Verification of cas no

The CAS Registry Mumber 1300740-34-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,0,7,4 and 0 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1300740-34:
(9*1)+(8*3)+(7*0)+(6*0)+(5*7)+(4*4)+(3*0)+(2*3)+(1*4)=94
94 % 10 = 4
So 1300740-34-4 is a valid CAS Registry Number.

Efficient synthesis of amino-protected calix[4]arenes selectively functionalized with iron chelator ICL670 designed as platform for iron recognition

experimental part, p. 2916 - 2924 (2011/05/13)

The development of selective electrochemical iron sensor is still a challenging task. One promising possibility is to use organically functionalized inorganic particles, for instance silica, as sensitive element. Herein, we report on the design and synthesis of calix[4]arene-based platforms modified with ICL670 iron chelator and alkylamino chain(s). These new molecular edifices could be easily grafted on silica particles. The strategy relies on selective calix[4]arenes functionalizations by alkylamino chains at the lower rim, in partial-cone or 1,3-alternate conformations. The different synthesis routes are presented and discussed.
