Check Digit Verification of cas no
The CAS Registry Mumber 93216-90-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,2,1 and 6 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 93216-90:
(7*9)+(6*3)+(5*2)+(4*1)+(3*6)+(2*9)+(1*0)=131
131 % 10 = 1
So 93216-90-1 is a valid CAS Registry Number.

Aminoaryl ketone photoinitiators
-
, (2008/06/13)
The photopolymerizable mixture described contains (A) at least one ethylenically unsaturated photopolymerisable compound, (B) a photoinitiator of the formula I STR1 and (C) a photosensitiser from the group of aromatic carbonyl compounds having a triplet energy of 225-310 kJ/mol, for example xanthones, thioxianthones, coumarins, phthalimides, phenones and the like. Ar is phenyl substituted in the 4-position by a substituted amino group, R1 and R2 are alkyl, R3 and R4 are alkyl or alkoxyalkyl, or R3 and R4 together are 3-oxapentamethylene. Said sensitisers (C) raise the activity of said photoinitiators (B) without shortening the shelf life of the mixtures. The photocurable mixtures are used especially as binders for printing inks or paints.
