Carbonic acid, with the chemical formula H2CO3, is a weak diprotic acid formed by the reaction of carbon dioxide (CO2) with water (H2O). It plays a crucial role in various natural processes, such as the carbon cycle and the regulation of blood pH. Copper(1++) salt, also known as copper(I) salt, refers to a group of compounds containing copper in the +1 oxidation state. These salts are typically formed by the reaction of copper metal with a suitable anion, such as chloride (CuCl) or cyanide (CuCN). Copper(I) salts are less common than their copper(II) counterparts and exhibit unique chemical properties, making them useful in various applications, including organic synthesis and as catalysts in chemical reactions.

Check Digit Verification of cas no

The CAS Registry Mumber 3444-14-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,4 and 4 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 3444-14:
(6*3)+(5*4)+(4*4)+(3*4)+(2*1)+(1*4)=72
72 % 10 = 2
So 3444-14-2 is a valid CAS Registry Number.
