53257-47-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 53257-47-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,2,5 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 53257-47:
(7*5)+(6*3)+(5*2)+(4*5)+(3*7)+(2*4)+(1*7)=119
119 % 10 = 9
So 53257-47-9 is a valid CAS Registry Number.

Samarium diiodide-induced reduction of amorphous selenium: A facile synthesis of diaryl diselenides
Zhang,Jia,Zhou
, p. 1247 - 1252 (2007/10/02)
Samarium diiodide reduces amorphous selenium to Se2/2- in THF. Subsequent addition of aryldiazonium fluoborates affords diaryl diselenides in moderate to good yields.
