Check Digit Verification of cas no

The CAS Registry Mumber 1263381-98-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,3,3,8 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1263381-98:
(9*1)+(8*2)+(7*6)+(6*3)+(5*3)+(4*8)+(3*1)+(2*9)+(1*8)=161
161 % 10 = 1
So 1263381-98-1 is a valid CAS Registry Number.

Metal cation-induced multifluorescence of azacrown-substituted (tetrafluorophenyl)imidazo[1,2-a]pyridine

Tanaka, Kiyoshi,Takeyama, Takashi,Yukawa, Ryousuke,Iwata, Satoru,Kurushima, Tohru

experimental part, p. 186 - 193 (2010/10/03)

ortho-Azacrown-substituted (tetrafluorophenyl)imidazo[1,2-a]pyridine (2) in an acetonitrile solution emits 380 nm light in the presence of Li+ cation and emits 460 nm light in the presence of Zn2+, Mg2+ or H+ cation. In contrast, para-azacrown-substituted analogue (1) emits three different fluorescent lights responding to Li+, Zn2+ or H+ cation, respectively; 388 nm light to Li+ cation, 433 nm light to Zn2+ cation or 469 nm light to H+ cation.
