Check Digit Verification of cas no

The CAS Registry Mumber 1565-25-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,6 and 5 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1565-25:
(6*1)+(5*5)+(4*6)+(3*5)+(2*2)+(1*5)=79
79 % 10 = 9
So 1565-25-9 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.
