Check Digit Verification of cas no
The CAS Registry Mumber 2320-38-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,2 and 0 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2320-38:
(6*2)+(5*3)+(4*2)+(3*0)+(2*3)+(1*8)=49
49 % 10 = 9
So 2320-38-9 is a valid CAS Registry Number.

PROCESS FOR SYNTHESIZING HALOGENATED DERIVATIVES OF FLUORESCEIN FOR USE IN THE PRODUCTION OF NON-VOLATILE MEMORY DEVICES
-
Page/Page column 7-8, (2008/06/13)
A process performs solid phase synthesis of halogenated derivatives of fluorescein, and includes reacting fluorescein with a halide MX, wherein M is an alkali metal and X is a halogen, and Oxone? (2 KHSO5.KHSO4.K2SO4), at a temperature higher than or equal to 150° C. A structure uses a halogenated derivative of fluorescein selected from the group consisting of 2′,4′,5′-trichlorofluorescein, 2′,4′,5′,7′-tetrachlorofluorescein, 4′,5′-diiodofluorescein diacetate and 2′,4′,5′-triiodofluorescein as electro-bistable material in a non-volatile memory device.
