Check Digit Verification of cas no

The CAS Registry Mumber 97634-84-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,6,3 and 4 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 97634-84:
(7*9)+(6*7)+(5*6)+(4*3)+(3*4)+(2*8)+(1*4)=179
179 % 10 = 9
So 97634-84-9 is a valid CAS Registry Number.

Thiopyranothiopyran Chemistry. 5. Synthesis of Dibenzothiopyranothiopyran-6,12-dione (Thioepindolidione)

Chen, Chin H.,Fox, John L.

, p. 3592 - 3595 (1985)

Tne novel thioepindolidione, a derivative of a thiopyranothiopyran, was synthesized from thiochroman-4-one.The absorption and fluorescence characteristics of thioepindolidione are compared with those of thioindigo and epindolidione.
