122430-79-9 Usage
Uses
Used in Ophthalmic Industry:
2-TERT-BUTYL-4-[3-(DIMETHYLVINYLSILANYL)PROPOXY]-6-(5-METHOXYBENZOTRIAZOL-2-YL)-PHENOL is used as a UV-light absorber for contact lenses. The application reason is to protect the eyes from harmful UV radiation, which can cause damage to the cornea and lead to various eye diseases, such as cataracts and macular degeneration. By incorporating this compound into contact lenses, users can enjoy the benefits of vision correction while also safeguarding their eyes from the sun's harmful rays.
Check Digit Verification of cas no
The CAS Registry Mumber 122430-79-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,4,3 and 0 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 122430-79:
(8*1)+(7*2)+(6*2)+(5*4)+(4*3)+(3*0)+(2*7)+(1*9)=89
89 % 10 = 9
So 122430-79-9 is a valid CAS Registry Number.
