Check Digit Verification of cas no
The CAS Registry Mumber 12772-98-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,7,7 and 2 respectively; the second part has 2 digits, 9 and 8 respectively.Calculate Digit Verification of CAS Registry Number 12772-98:
(7*1)+(6*2)+(5*7)+(4*7)+(3*2)+(2*9)+(1*8)=114
114 % 10 = 4
So 12772-98-4 is a valid CAS Registry Number.

Indium extraction from synthetic indium-bearing zinc ferrite (IBZF) was investigated using sulfur dioxide as a reductant in sulfuric acid medium, and the recovery of indium and the full use of sulfur dioxide were achieved. The leaching kinetics of indium from synthetic IBZF were studied, and the...detailed
Most caves owe their origin to carbonic acid generated in the soil. In contrast, sulfuric acid caves are produced by the oxidation of sulfides beneath the surface. Although sulfuric acid caves are relatively few, they include some large and well-known examples, such as Carlsbad Cavern, New Mexic...detailed
In Italy, especially along the Apennine Chain, numerous active and inactive sulfuric acid speleogenetic (SAS) caves have been documented in the last two decades. Here we present an overview of these peculiar hypogene systems, illustrating their main geomorphological and mineralogical features, a...detailed
Sulfur stable isotopes from cave sulfates (mainly gypsum) have been used in a number of studies to trace the source of sulfur in caves formed by sulfuric acid, but only few studies apply combined use of sulfur and oxygen stable isotopes to further understand the processes operating in sulfuric a...detailed
We used a nanofiltration (NF) membrane process to produce purified aqueous sulfuric acid from copper-refining sulfuric acid wastewater. Wastewater generated from a copper-refining process was used to explore the membrane performances and acid stabilities of six commercial NF membranes. A combina...detailed
