Check Digit Verification of cas no
The CAS Registry Mumber 1401253-09-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,1,2,5 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1401253-09:
(9*1)+(8*4)+(7*0)+(6*1)+(5*2)+(4*5)+(3*3)+(2*0)+(1*9)=95
95 % 10 = 5
So 1401253-09-5 is a valid CAS Registry Number.

One-pot synthesis of 5-arylamino-1,3,4-selenadiazol-2(3H)-ones from arylisoselenocyanates
Xie, Yuanyuan,Yang, Ping,Chen, Xiaodong
, p. 421 - 424 (2012/09/22)
A one-pot reaction of arylisoselenocyanates, hydrazine and bis(trichloromethyl) carbonate, in the presence of a base provides an efficient route for the synthesis of 5-arylamino-1,3,4-selenadiazol-2(3H)-ones in good to excellent yields. A plausible mechan
