Check Digit Verification of cas no

The CAS Registry Mumber 52448-69-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,4,4 and 8 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 52448-69:
(7*5)+(6*2)+(5*4)+(4*4)+(3*8)+(2*6)+(1*9)=128
128 % 10 = 8
So 52448-69-8 is a valid CAS Registry Number.

Highly efficient iron(II) chloride/N-bromosuccinimide-mediated synthesis of imides and acylsulfonamides

Wang, Feng,Liu, Hongxia,Fu, Hua,Jiang, Yuyang,Zhao, Yufen

supporting information; experimental part, p. 246 - 252 (2009/09/05)

We have developed a general and highly efficient iron(II) chloride/N-bromosuccinimide (NBS)-mediated method for the synthesis of imides and acylsulfonamides via couplings of thioesters with carboxamides/sulfonamides, and the method is simple, economical and shows practical advantages.
