17647-57-3 Usage
General Description
1-Dichloromethyl-2-methoxybenzene, also known as o-dichlorobenzene and 2-methoxy-1-dichloromethylbenzene, is an organic compound with the chemical formula C8H8Cl2O. It is a colorless liquid with a sweet, chloroform-like odor that is commonly used as a fumigant and pesticide. It is also used in the production of dyes, resins, and pharmaceuticals. Exposure to 1-Dichloromethyl-2-methoxybenzene can cause irritation to the skin, eyes, and respiratory system, and prolonged exposure may result in more serious health effects. It is important to handle and store this chemical with caution and follow proper safety procedures when working with it.
Check Digit Verification of cas no
The CAS Registry Mumber 17647-57-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,6,4 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 17647-57:
(7*1)+(6*7)+(5*6)+(4*4)+(3*7)+(2*5)+(1*7)=133
133 % 10 = 3
So 17647-57-3 is a valid CAS Registry Number.

Formamide Catalysis Facilitates the Transformation of Aldehydes into Geminal Dichlorides
Huy, Peter Helmut
supporting information, p. 2474 - 2483 (2019/06/08)
Herein, a novel method for the transformation of aldehydes into geminal dichlorides based on phthaloyl chloride as reagent and N -formylpyrrolidine as Lewis base catalyst is disclosed. Given the mild reaction conditions, the current protocol is distinguished by high levels of functional group compatibility and scalability and is operationally simple. The in situ formation of a Vilsmeier Haack reagent type intermediate is likely to be essential for this organocatalytic nucleophilic substitution reaction.
