339-38-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 339-38-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,3 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 339-38:
(5*3)+(4*3)+(3*9)+(2*3)+(1*8)=68
68 % 10 = 8
So 339-38-8 is a valid CAS Registry Number.

Ultrasound accelerated sulfonylation of amines by p-acetamidobenzenesulfonyl chloride using Mg–Al hydrotalcite as an efficient green base catalyst

Truong, Binh Nhat,Le, Luong Huu,Chau, Duy-Khiem Nguyen,Duus, Fritz,Luu, Thi?Xuan?Thi

, p. 515 - 528 (2016/10/03)

The sulfonylation reaction of various aliphatic, alicyclic, aromatic, and hetero-aromatic amines with p-acetamidobenzenesulfonyl chloride has been investigated using different types of base catalysis under varied reaction conditions. Mg–Al hydrotalcite, characterizable as an inexpensive, reusable, and green solid catalyst, was found to be the most efficient catalyst, when the reaction is carried out in a minimum volume of solvent (acetone). The reaction was found to be accelerated drastically with the support of ultrasound irradiation, affording the sulfonamides in yields better or equivalent to those obtained under the longer lasting conventional stirring conditions.
