Check Digit Verification of cas no

The CAS Registry Mumber 1072902-45-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,7,2,9,0 and 2 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1072902-45:
(9*1)+(8*0)+(7*7)+(6*2)+(5*9)+(4*0)+(3*2)+(2*4)+(1*5)=134
134 % 10 = 4
So 1072902-45-4 is a valid CAS Registry Number.

Synthesis and characterization of coumarin-based spiropyran photochromic colorants

Chen, Jhih-Rong,Wong, Jen-Bing,Kuo, Pei-Yu,Yang, Ding-Yah

supporting information; experimental part, p. 4823 - 4826 (2009/06/05)

(Equation Presented) Two coumarin-based spiropyran derivatives were synthesized and characterized in two steps to explore their photochromic properties. Both prepared compounds are sensitive to UV light and change colors upon irradiation. The resulting photogenerated zwitterions revert to the original compounds while being heated. A new family of organic photochromic colorants is introduced.
