Check Digit Verification of cas no

The CAS Registry Mumber 57049-36-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,0,4 and 9 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 57049-36:
(7*5)+(6*7)+(5*0)+(4*4)+(3*9)+(2*3)+(1*6)=132
132 % 10 = 2
So 57049-36-2 is a valid CAS Registry Number.

Anomalous Photochromism and Photochemical Cation-binding Control of Crowned Malachite Green Leuconitrile Based on Intramolecular Electrostatic Repulsion

Kimura, Keiichi,Kaneshige, Masayuki,Yokoyama, Masaaki

, p. 1103 - 1104 (1994)

A Malachite Green leuconitrile incorporating a crown-ether moiety has been designed, exhibiting anomalous photochromism and photoinduced switching of cation binding on the basis of intramolecular repulsive interaction between its crown-complexed metal ion and photoionized cationic species.
