4982-02-9 Usage
Description
(1,3-diphenyl-2-imidazolidinyl)(phenyl)methanone, commonly known as DMDM hydantoin, is a white, crystalline solid preservative used in personal care and cosmetic products. It dissolves in water to form a clear solution and releases formaldehyde, which inhibits the growth of bacteria and mold.
Uses
Used in Personal Care and Cosmetic Products:
DMDM hydantoin is used as a preservative in various personal care and cosmetic products, such as shampoos, conditioners, lotions, and soaps, to prevent the growth of bacteria and mold, ensuring the safety and longevity of these products.
However, it has been associated with causing allergic reactions in some individuals and has raised concerns about its potential health effects. As a result, some companies have chosen to avoid using DMDM hydantoin in their products, while others continue to use it within regulatory limits.
Check Digit Verification of cas no
The CAS Registry Mumber 4982-02-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,8 and 2 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4982-02:
(6*4)+(5*9)+(4*8)+(3*2)+(2*0)+(1*2)=109
109 % 10 = 9
So 4982-02-9 is a valid CAS Registry Number.

Breslow intermediates, first postulated in 1958, are pivotal intermediates in carbene-catalyzed umpolung. Attempts to isolate and characterize these fleeting amino enol species first met with success in 2012 when we found that saturated bis-Dipp/Mes imida
