Check Digit Verification of cas no

The CAS Registry Mumber 910915-20-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,0,9,1 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 910915-20:
(8*9)+(7*1)+(6*0)+(5*9)+(4*1)+(3*5)+(2*2)+(1*0)=147
147 % 10 = 7
So 910915-20-7 is a valid CAS Registry Number.

Diimines and secondary diamines

-

Page/Page column 14-15, (2008/06/13)

This invention provides aromatic diimines which have imino hydrocarbylidene groups with at least two carbon atoms, and aromatic secondary diamines which have amino hydrocarbyl groups with at least two carbon atoms. Both the aromatic diimines and the aromatic secondary diamines either are in the form of one phenyl ring, or are in the form of two phenyl rings connected by an alkylene bridge; each position ortho to an imino group or an amino group bears a hydrocarbyl group. When in the form of one phenyl ring, there are two imino groups on the ring or two amino groups on the ring; the imino groups or amino groups are meta or para relative to each other. When in the form of two phenyl rings connected by an alkylene bridge, there is either one imino group or one amino group on each phenyl ring. Also provided are processes for forming diimines and secondary diamines.
