82583-54-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82583-54-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,5,8 and 3 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 82583-54:
(7*8)+(6*2)+(5*5)+(4*8)+(3*3)+(2*5)+(1*4)=148
148 % 10 = 8
So 82583-54-8 is a valid CAS Registry Number.

Pummerer reaction of sulfoxides in acetic anhydride catalyzed by Al-MCM-41
Ito, Suguru,Kubota, Yoshihiro,Asami, Masatoshi
, p. 16 - 18 (2016/01/20)
The Pummerer reaction of acetic anhydride with both alkyl aryl sulfoxides and dialkyl sulfoxides was efficiently promoted by a mesoporous aluminosilicate Al-MCM-41 to afford the corresponding α-acetoxy sulfides in high yields. The catalyst was easily reco
