Eusol is a chemical solution primarily used for preserving and fixing biological specimens, particularly in histology and cytology. It is composed of a mixture of formaldehyde, glacial acetic acid, and ethanol in distilled water, with the typical ratio being 75% formaldehyde, 5% glacial acetic acid, and 20% ethanol. Eusol's main function is to prevent decay and maintain the structure of cells and tissues, making it an essential component in the preparation of samples for microscopic examination. The solution's effectiveness in preserving specimens is attributed to its ability to denature proteins and cross-link them, thus preventing further degradation.
The CAS Registry Mumber 8047-82-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 8,0,4 and 7 respectively; the second part has 2 digits, 8 and 2 respectively. Calculate Digit Verification of CAS Registry Number 8047-82: (6*8)+(5*0)+(4*4)+(3*7)+(2*8)+(1*2)=103 103 % 10 = 3 So 8047-82-3 is a valid CAS Registry Number.
