Check Digit Verification of cas no
The CAS Registry Mumber 119-19-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 119-19:
(5*1)+(4*1)+(3*9)+(2*1)+(1*9)=47
47 % 10 = 7
So 119-19-7 is a valid CAS Registry Number.

Azo dyestuffs
-
, (2008/06/13)
Azo dyestuffs, which in the acid form, are represented by the formula: wherein A is an aromatic radical, M is a 1,4-benzene radical which may be substituted, E is the residue of a coupling component which is free from azo groups, At least one of A and M containing a phosphonic acid group, and the metal complexes of those having a metallisable group are reactive dyes suitable for use in the process of German OLS No. 2324809.
