80296-78-2 Usage
General Description
Cresol-formaldehyde copolymer (1,2-naphthoquinonediazido-4-sulfonate) is a chemical compound renowned in the industry where it is often used as a photoresist, primarily in the manufacture of semiconductor devices and other microfabricated components. This copolymer's unique properties allow it to function as a photosensitizer that decomposes in the presence of light, making it ideal for use in reprography technologies. Its stability and patterning precision make it a critical aspect of semi-conductor fabrication. As with most chemicals, appropriate precautions must be taken when handling to ensure safety due to its toxic nature.
Check Digit Verification of cas no
The CAS Registry Mumber 80296-78-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,2,9 and 6 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 80296-78:
(7*8)+(6*0)+(5*2)+(4*9)+(3*6)+(2*7)+(1*8)=142
142 % 10 = 2
So 80296-78-2 is a valid CAS Registry Number.
