2216-41-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2216-41-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,1 and 6 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2216-41:
(6*2)+(5*2)+(4*1)+(3*6)+(2*4)+(1*1)=53
53 % 10 = 3
So 2216-41-3 is a valid CAS Registry Number.

Conversion of trimethylsilyl ethers to acetyl or formyl esters with TiCl4

Iranpoor, Nasser,Zeynizadeh, Behzad

, p. 2123 - 2128 (1999)

A simple method is described for the efficient conversion of trimethylsilyl ethers to their corresponding acetyl and formyl esters in refluxing ethyl acetate or ethyl formate in the presence of TiCl4.

Formylation of amines and alcohols using aminopropylated mesoporous SBA-15 silica (APMS) as an efficient and recyclable catalyst

Malakooti, Reihaneh,Sobhani, Sara,Razavi, Nasrin,Shafiei, Soheila,Mokhtari, Rezvan

experimental part, p. 1979 - 1990 (2012/04/17)

Aminopropylated mesoporous SBA-15 silica (APMS) is introduced as a new, recyclable and efficient catalyst for the formylation of a variety of amines and alcohols by using readily available formic acid under solvent-free conditions.

Silphos [PCl3-n(SiO2)n]: A heterogeneous phosphine reagent for formylation and acetylation of alcohols and amines with ethyl formate and acetate

Iranpoor, Nasser,Firouzabadi, Habib,Jamalian, Arezu

, p. 7963 - 7966 (2007/10/03)

Alcohols and amines are formylated and acetylated in the presence of Silphos [PCl3-n(SiO2)n] in ethyl formate and ethyl acetate in high to excellent yields. This procedure provides a method to separate the product by a simple filtration.
