1131647-12-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1131647-12-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,1,6,4 and 7 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1131647-12:
(9*1)+(8*1)+(7*3)+(6*1)+(5*6)+(4*4)+(3*7)+(2*1)+(1*2)=115
115 % 10 = 5
So 1131647-12-5 is a valid CAS Registry Number.

Thiaoxaaza-macrocyclic chromoionophores as mercury(II) sensors: Synthesis and color modulation
Lee, Hayan,Lee, Shim Sung
, p. 1393 - 1396 (2009)
Azo-coupled macrocyclic chromoionophores incorporating benzene (L 1) and pyridine (L2) subunits were synthesized, respectively. In a cation-induced color change experiment, both receptors showed Hg2+ selectivity. However,
