Check Digit Verification of cas no

The CAS Registry Mumber 78749-99-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,7,4 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 78749-99:
(7*7)+(6*8)+(5*7)+(4*4)+(3*9)+(2*9)+(1*9)=202
202 % 10 = 2
So 78749-99-2 is a valid CAS Registry Number.

An effcient synthesis of 2-aminobenzoxazoles and 2-aminobenzothiazazoles from 2-aminophenols or 2-aminothiophenols and isoselenocyanates

Xie, Yuanyuan,Zhang, Fan,Chen, Xiaodong,Li, Jianjun

experimental part, p. 2087 - 2096 (2011/03/23)

An expeditious method to access 2-aminobenzoxazoles and 2-aminobenzothiazoles from various substituted 2-aminophenols and 2-aminothiophenols, respectively, with isoselenocyanates in a one pot procedure is reported. Elemental Se precipitates nearly quantitatively in the reaction without any deselenizing agent and it can be reused. A possible mechanism for the formation of the target products is proposed.
