Check Digit Verification of cas no

The CAS Registry Mumber 24752-26-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,7,5 and 2 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 24752-26:
(7*2)+(6*4)+(5*7)+(4*5)+(3*2)+(2*2)+(1*6)=109
109 % 10 = 9
So 24752-26-9 is a valid CAS Registry Number.

Novel synthesis of 2-aminobenzimidazoles from isoselenocyanates

Xie, Yuanyuan,Zhang, Fan,Li, Jianjun,Shi, Xiangjun

supporting information; experimental part, p. 901 - 904 (2010/07/06)

An efficient one-pot procedure for the synthesis of 2-aminobenzimidazoles from isoselenocyanates and various substituted diamines is described. Precipitation of elemental selenium from the reaction mixture greatly simplifies the purification procedure and also allows it to be re-used for preparation of isoseleno?cyanates. A possible mechanism for the formation of 2-aminobenzimidazoles is proposed. Georg Thieme Verlag Stuttgart - New York.
