Check Digit Verification of cas no
The CAS Registry Mumber 4976-44-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,7 and 6 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4976-44:
(6*4)+(5*9)+(4*7)+(3*6)+(2*4)+(1*4)=127
127 % 10 = 7
So 4976-44-7 is a valid CAS Registry Number.

, (2008/06/13)
This invention relates to 3,7-bis(disubstituted aminophenyl- or indolyl)-3,7-bis(diphenylamino)pyromellitides, 3,5-bis(disubstituted aminophenyl- or indolyl)-3,5-bis(diphenylamino)pyromellitides and mixtures thereof useful as color formers, particularly in carbonless duplicating and thermal marking systems, which are prepared by the interaction of 2,5-bis(disubstituted aminophenyl- or indolyl)carbonyl-1,4-benzenedicarboxylic acids or 2,4-bis(disubstituted aminophenyl- or indolyl)carbonyl-1,5-benzenedicarboxylic acids and mixtures thereof with diphenylamines.
