General Description
Lithium carmine is a chemical compound that is a lithium salt of carminic acid. It is a red dye that is frequently used in histology, the study of the microscopic structure of tissues. Lithium carmine stains nuclei and chromosomes, making it useful for highlighting these structures in cells. It is often used in combination with other dyes to achieve a specific staining pattern. Due to its ability to selectively bind to specific cellular components, lithium carmine is a valuable tool in biological research and medical diagnostics.
Check Digit Verification of cas no
The CAS Registry Mumber 12772-56-4 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, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 12772-56:
(7*1)+(6*2)+(5*7)+(4*7)+(3*2)+(2*5)+(1*6)=104
104 % 10 = 4
So 12772-56-4 is a valid CAS Registry Number.
