176543-06-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 176543-06-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,6,5,4 and 3 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 176543-06:
(8*1)+(7*7)+(6*6)+(5*5)+(4*4)+(3*3)+(2*0)+(1*6)=149
149 % 10 = 9
So 176543-06-9 is a valid CAS Registry Number.

Stereoselective Synthesis of (E)-1-Halo-2-arylselanylethylenes via Hydrozirconation of Arylselanylethynes
Zhu, Liu-Sheng,Huang, Zhi-Zhen,Huang, Xian
, p. 112 - 113 (2007/10/03)
Hydrozirconation of arylselanylethynes gives zirconium(iv) complexes, which are trapped with iodine or N-bromosuccinimide to afford (E)-1-halo-2-arylselanylethylenes.
