Check Digit Verification of cas no
The CAS Registry Mumber 62669-67-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,6,6 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 62669-67:
(7*6)+(6*2)+(5*6)+(4*6)+(3*9)+(2*6)+(1*7)=154
154 % 10 = 4
So 62669-67-4 is a valid CAS Registry Number.

MAGENTA DYES AND THEIR PREPARATION METHODS AND APPLICATIONS
-
Paragraph 0147; 0156, (2014/07/23)
The present invention relates to a class of magenta dyes, their preparation methods and applications. The magenta dyes include the compounds which simultaneously contain carboxyl group, sulfonic acid group and the carbonyl propyl sulfurylsulfonic acid on the anthrapyridone skeleton, showing in the form of general formula (I) or their mixtures. In the general formula (I): A may be cation M4, or substituted or unsubstituted benzyl group, or substituted or unsubstituted naphthyl methyl; M1, M2, M3 are respectively cation or cationic groups; Sulfonic acid group (SO3M2)m may located any position of the benzene ring, of which m is an integer of 0-2. As containing carboxyl (or carboxylic benzyl ester or naphthoate), sulfonic acid groups and carbonyl propyl sulfuryl simultaneously, the magenta dyes of the present invention feature outstanding tone, brightness, light resistance, water resistance, ozone resistance as well as solubility and solution stability, etc.
