Check Digit Verification of cas no

The CAS Registry Mumber 1187973-86-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,7,9,7 and 3 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1187973-86:
(9*1)+(8*1)+(7*8)+(6*7)+(5*9)+(4*7)+(3*3)+(2*8)+(1*6)=219
219 % 10 = 9
So 1187973-86-9 is a valid CAS Registry Number.

Dendrimers and Dendrimer Applications

-

Page/Page column 19, (2011/10/02)

An activatable functionalised Nth generation dendrimer having: a core comprising a first monomer having at least two carboxylic acid functional groups; and N successive generations, where N=0 to 10, wherein each generation comprises: a second monomer having at least two alcohol functional groups, wherein at least one alcohol group is bonded to a carboxylic acid group of the first monomer of the prior generation, and an additional first monomer attached to a second alcohol function group of said second monomer of that generation; and the final generation having attached thereto at said second alcohol functional group of said second monomer, a moiety having a dicarboxylic acid functional group, activatable by treatment with a carboxylic acid activating reagent such that reactivity of the carboxylic acid functional group is increased. The dendrimer, when activated, may be used in applications such as polymer crosslinking and/or nanoshell production.
