Check Digit Verification of cas no
The CAS Registry Mumber 6883-99-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,8,8 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6883-99:
(6*6)+(5*8)+(4*8)+(3*3)+(2*9)+(1*9)=144
144 % 10 = 4
So 6883-99-4 is a valid CAS Registry Number.

Page/Page column 6, (2010/04/23)
The present invention concerns dyes of the general formula I where X and Y represent hydrogen, bromine or chlorine, but not simultaneously hydrogen;R represents F, Cl, Br, COOR1 or CF3;R′ represents H or F;R1 represents C1-C6-alkyl; andone of W1 and W2 represents hydroxyl and the other nitro and Y is always ortho to the hydroxyl group;but not compounds in which R represents Cl attached to the phenyl nucleus in a is position ortho to the NH group nor compounds in which W1 represents nitro, W2 represents hydroxyl, Y represents hydrogen, X represents chlorine and R represents bromine attached to the phenyl nucleus in a position meta to the NH group, mixtures with further dyes, and also their preparation and use.
