Check Digit Verification of cas no
The CAS Registry Mumber 89691-80-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,6,9 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 89691-80:
(7*8)+(6*9)+(5*6)+(4*9)+(3*1)+(2*8)+(1*0)=195
195 % 10 = 5
So 89691-80-5 is a valid CAS Registry Number.

Synthesis and Properties of Some 7-Dimethylamino-1,4-benzoxazin-2-ones
Bris, Marie-Therese
, p. 1275 - 1280 (2007/10/02)
The synthesis of the 7-dimethylamino-1,4-benzoxazin-2-ones (5), fluorescent dyes, by condensing α-ketoacids with 2-amino-5-dimethylaminophenol is described.When the 3-substituent is a methyl group, these compounds can be further condensed with aromatic aldehydes to provide the styryl dyes (6).These products are easily opened by hydrochloric acid in ethanolic solution to afford the corresponding benzalketoacid ethyl esters (7).
