Check Digit Verification of cas no

The CAS Registry Mumber 544710-22-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,4,7,1 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 544710-22:
(8*5)+(7*4)+(6*4)+(5*7)+(4*1)+(3*0)+(2*2)+(1*2)=137
137 % 10 = 7
So 544710-22-7 is a valid CAS Registry Number.

Synthesis and comparison of hyperbranched aromatic polyimides having the same repeating unit by AB2 self-polymerization and A2 + B3 polymerization

Hao, Jianjun,Jikei, Mitsutoshi,Kakimoto, Masa-Aki

, p. 3519 - 3528 (2007/10/03)

A new AB2 monomer, designed from a template of the repeating unit of the hyperbranched polyimides by nonideal A2 + B3 polymerization, was successfully prepared via a multistep synthesis. Hyperbranched polyimides, having th

Preparation of hyperbranched aromatic polyimides via A2 + B3 approach

Hao, Jianjun,Jikei, Mitsutoshi,Kakimoto, Masa-Aki

, p. 5372 - 5381 (2007/10/03)

Two novel B3 monomers, tri(phthalic anhydride) and tri(phthalic acid methyl ester), were synthesized. Hyperbranched polyimides were prepared by A2 + B3 polymerizations of (a) 1,4-phenylenediamine (A2) and tri(ph
