Check Digit Verification of cas no

The CAS Registry Mumber 1165820-52-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,5,8,2 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1165820-52:
(9*1)+(8*1)+(7*6)+(6*5)+(5*8)+(4*2)+(3*0)+(2*5)+(1*2)=149
149 % 10 = 9
So 1165820-52-9 is a valid CAS Registry Number.

Facile synthesis of second-generation dendrons with an orthogonal functional group at the focal point

Cheedarala, Ravi Kumar,Sunkara, Vijaya,Park, Joon Won

experimental part, p. 1966 - 1980 (2009/10/24)

Facile synthesis of second-generation dendrons with an aldehyde, epoxy, or t-Boc group at the focal point and nine carboxylic acid groups at the periphery is reported. The scheme includes a coupling of the first-generation dendrons and a two-step, one-pot reaction that proceeds through a Boc deprotection and in situ conjugation at the focal point.
