General Description
Chromium(II) bromide, with the chemical formula CrBr2, is a compound composed of one chromium ion bonded to two bromide ions. It is a dark green, crystalline solid at room temperature and is highly hygroscopic, meaning it readily absorbs moisture from the air. Chromium(II) bromide is used in a variety of chemical reactions, particularly as a catalyst in organic synthesis. It is also used in the production of other chromium compounds and as a reagent in the study of coordination chemistry. However, it is important to handle chromium(II) bromide with care, as it is toxic and poses health hazards if inhaled or ingested.
Check Digit Verification of cas no
The CAS Registry Mumber 10049-25-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,0,4 and 9 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 10049-25:
(7*1)+(6*0)+(5*0)+(4*4)+(3*9)+(2*2)+(1*5)=59
59 % 10 = 9
So 10049-25-9 is a valid CAS Registry Number.
