Check Digit Verification of cas no

The CAS Registry Mumber 528604-89-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,2,8,6,0 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 528604-89:
(8*5)+(7*2)+(6*8)+(5*6)+(4*0)+(3*4)+(2*8)+(1*9)=169
169 % 10 = 9
So 528604-89-9 is a valid CAS Registry Number.

Synthesis and photochromic properties of functional diarylethene with a 2,5-dihydrothiophene bridging unit

Chen, Yi,Zeng, De X.,Fan, Mei G.

, p. 1435 - 1437 (2007/10/03)

(Matrix presented) A novel synthetic route to symmetric and nonsymmetric dithienylethene derivatives with a 2,5-dihydrothiophene bridging unit was described. A class of new functional photochromic compounds was prepared and showed photochromic properties similar to those of known diarylethenes.
