5-(3,4-Dimethoxybenzylidene)hydantoin is a chemical compound that is commonly used as an antimicrobial agent in personal care products and cosmetics. It is a hydantoin derivative, which means it contains a five-membered ring structure with two nitrogen atoms. The compound has been found to exhibit strong antimicrobial activity against a wide range of microorganisms, making it an effective preservative in various formulations. Additionally, 5-(3,4-Dimethoxybenzylidene)hydantoin is known for its stability and compatibility with other ingredients, making it a popular choice for enhancing the shelf life and safety of consumer products. However, it is important to note that this chemical may cause skin irritation and allergic reactions in some individuals, so it is important to use it in controlled concentrations.
Check Digit Verification of cas no
The CAS Registry Mumber 10040-91-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,0,4 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 10040-91:
(7*1)+(6*0)+(5*0)+(4*4)+(3*0)+(2*9)+(1*1)=42
42 % 10 = 2
So 10040-91-2 is a valid CAS Registry Number.

In this study, a chemoenzymatic synthesis method for the production of L-3,4-dimethoxyphenyl-alanine and its analogues from phenylpyruvate derivatives was developed. The aspartate aminotransferase from Escherichia coli was engineered by error prone PCR and the improved variants were identified. When 3, 4-dimethoxy phenylpyruvate was added by fed-batch on a preparative scale, L-3,4-dimethoxyphenyl-alanine was formed in 95.4% conversion and > 99% ee with the best aspartate aminotransferase variant as the catalyst. This study provided an efficient method for the production of methoxy substituted phenylalanines using the engineered aspartate aminotransferase.
