Check Digit Verification of cas no

The CAS Registry Mumber 491875-12-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,1,8,7 and 5 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 491875-12:
(8*4)+(7*9)+(6*1)+(5*8)+(4*7)+(3*5)+(2*1)+(1*2)=188
188 % 10 = 8
So 491875-12-8 is a valid CAS Registry Number.

Ammonium-bearing dinuclear copper(II) complex: A highly selective and sensitive colorimetric probe for pyrophosphate

Yu, Wenxiang,Qiang, Jian,Yin, Jun,Kambam, Srinivasulu,Wang, Fang,Wang, Yong,Chen, Xiaoqiang

supporting information, p. 2220 - 2223 (2014/05/06)

Two dinuclear copper complexes with and without ammonium moieties were synthesized. The complexes exhibited selective binding affinity to pyrophosphate in aqueous solution. The dinuclear copper complex, with ammonium arms, showed a ca. 527-fold enhancement in pyrophosphate binding affinity compared with its analogue without ammonium units.
