Check Digit Verification of cas no

The CAS Registry Mumber 54522-28-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,5,2 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 54522-28:
(7*5)+(6*4)+(5*5)+(4*2)+(3*2)+(2*2)+(1*8)=110
110 % 10 = 0
So 54522-28-0 is a valid CAS Registry Number.

Partially bio-based polyimides from isohexide-derived diamines

Ji, Xiaodong,Wang, Zikun,Yan, Jingling,Wang, Zhen

, p. 38 - 45 (2015/08/24)

Abstract Novel partially bio-based polyimides were prepared from 2, 5-diamino-2, 5-dideoxy-1, 4: 3, 6-dianhydrosorbitol (diaminoisosorbide, DAIS) dihydrochloride, 2, 5-diamino-2, 5-dideoxy-1, 4: 3, 6-dianhydroiditol (diaminoisoidide, DAII) dihydrochloride

MONOFLUORINATED DERIVATIVES OF DIANHYDROHEXITOLS AND PROCESSES FOR MAKING THE SAME

-

Paragraph 0041; 0042, (2014/01/08)

Novel monofluoro analogs of isosorbide, isomannide and isoidide are described, together with processes for making such monofluoro analogs.

Renewable rigid diamines: Efficient, stereospecific synthesis of high purity isohexide diamines

Thiyagarajan, Shanmugam,Gootjes, Linda,Vogelzang, Willem,Van Haveren, Jacco,Lutz, Martin,Van Es, Daan S.

experimental part, p. 1823 - 1829 (2012/04/04)

We report an efficient three-step strategy for synthesizing rigid, chiral isohexide diamines derived from 1,4:3,6-dianhydrohexitols. These biobased chiral building blocks are presently the subject of several investigations (in our and several other groups
