551910-81-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 551910-81-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,1,9,1 and 0 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 551910-81:
(8*5)+(7*5)+(6*1)+(5*9)+(4*1)+(3*0)+(2*8)+(1*1)=147
147 % 10 = 7
So 551910-81-7 is a valid CAS Registry Number.

Synthesis of aliphatic polyamide dendrimers based on facile convergent method
Ito, Yumiko,Higashihara, Tomoya,Ueda, Mitsuru
, p. 4175 - 4183 (2012)
A novel and rapid approach for the synthesis of aliphatic polyamide dendrimers, consisting of the 3,4-dialkoxyhydrocinnamamide structure as a repeating unit, has been developed. Aliphatic polyamide dendrons and dendrimers were easily prepared by a converg
