Check Digit Verification of cas no

The CAS Registry Mumber 15091-91-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,0,9 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 15091-91:
(7*1)+(6*5)+(5*0)+(4*9)+(3*1)+(2*9)+(1*1)=95
95 % 10 = 5
So 15091-91-5 is a valid CAS Registry Number.

Tricalcium aluminate hydration in the presence of CALCIUM SULFITE (cas 15091-91-5) hemihydrate07/30/2019

This article reports on the study to evaluate the potential possibility of regulating the tricalcium aluminate (C3A) hydration process by the addition of calcium sulfite hemihydrate. The kind and the form of hydration products were studied in the system: C3A–CaSO3·0.5H2O–H2O and C3A–CaSO3·0...detailed

Direct transformation of CALCIUM SULFITE (cas 15091-91-5) to α-calcium sulfate hemihydrate in a concentrated Ca–Mg–Mn chloride solution under atmospheric pressure07/27/2019

Massive quantities of sulfite-rich flue gas desulfurization (FGD) scrubber sludge have been generated by coal burning power plants. Utilization of the sulfite-rich sludge for preparing α-calcium sulfate hemihydrate (α-HH), an important kind of cementitious material, is of particular interest t...detailed

Transformation pathways from CALCIUM SULFITE (cas 15091-91-5) to α-calcium sulfate hemihydrate in concentrated CaCl2 solutions07/25/2019

The disposal of sulfite-rich flue gas desulfurization (FGD) scrubber sludge has been a tough problem. The sludge now finds its prospective utilization way by being transformed into α-calcium sulfate hemihydrate (α-HH). At low pH, atmospheric pressure and 95.0 °C, the calcium sulfite hemihydra...detailed

Conversion of CALCIUM SULFITE (cas 15091-91-5) waste to hydroxyapatite07/24/2019

Calcium sulfite waste was successfully transformed to hydroxyapatite (HAp) by oxidation using H2O2, followed by reaction with (NH4)2HPO4 under an NH4OH atmosphere. A single phase hydroxyapatite was obtained by stirring at 60, 80, or 100 °C rather than by hydrothermal treatment at 150 °C. Such ...detailed
