Phenosafranin is a synthetic dye that belongs to the class of phenoxazone dyes, characterized by its bright red color. It is commonly used as a pH indicator, changing from colorless to red as the pH increases from acidic to basic conditions. Phenosafranin is also utilized in histology and cytology for staining cellular structures, particularly the cytoplasm and nucleic acids, due to its affinity for acidic substances. It is important to note that phenosafranin is not suitable for staining neutral or basic substances, and its use in biological applications is subject to safety considerations and proper handling protocols.

Check Digit Verification of cas no

The CAS Registry Mumber 4607-70-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,0 and 7 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4607-70:
(6*4)+(5*6)+(4*0)+(3*7)+(2*7)+(1*0)=89
89 % 10 = 9
So 4607-70-9 is a valid CAS Registry Number.
