Cresyl violet, also known as cresyl violet acetate or 1-(4-dimethylaminobenzene)-4-(4-dimethylaminostyryl)pyridinium dibromide, is a synthetic, water-soluble dye commonly used as a histological stain in neuroscience and pathology. It is particularly effective in staining the cell nuclei of neurons, making it a valuable tool for visualizing the structure and organization of the nervous system. Cresyl violet is known for its ability to penetrate cell membranes and bind to the negatively charged DNA within the cell nuclei, resulting in a deep violet coloration. This staining property allows researchers to differentiate between various types of tissue and to study the morphology and distribution of neurons in brain sections. The dye is also used in the diagnosis of certain neurological disorders and in the assessment of brain damage.

Check Digit Verification of cas no

The CAS Registry Mumber 7370-62-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,7 and 0 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 7370-62:
(6*7)+(5*3)+(4*7)+(3*0)+(2*6)+(1*2)=99
99 % 10 = 9
So 7370-62-9 is a valid CAS Registry Number.
