Check Digit Verification of cas no

The CAS Registry Mumber 128439-62-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,4,3 and 9 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 128439-62:
(8*1)+(7*2)+(6*8)+(5*4)+(4*3)+(3*9)+(2*6)+(1*2)=143
143 % 10 = 3
So 128439-62-3 is a valid CAS Registry Number.

Synthesis and characterization of bis-and tris-(4-carboxybenzoyl)- alkaneamines

Guarda,Parra,Chavez,Belmar,Jimenez,Pasan,Ruiz-Perez

, p. 1305 - 1308 (2013/03/28)

A practical and efficient protocol to obtain bis- and tris-(4- carboxybenzoyl)alkaneamines based on monoprotected 1,4-benzenedicarboxylic acid is reported here. N-(4-methoxycarbonylbenzoyloxy)succinimide was treated with aliphatic diamines and triamines to form aliphatic hydrocarbon-linked bis- and tris-amides 4a-4e. The yields ranged from good to very good and showed that choosing the right acylating agent is a key point in this synthesis. All the compounds were characterized by elemental analysis, FTIR, and 1H NMR.
