1025969-70-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1025969-70-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,5,9,6 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1025969-70:
(9*1)+(8*0)+(7*2)+(6*5)+(5*9)+(4*6)+(3*9)+(2*7)+(1*0)=163
163 % 10 = 3
So 1025969-70-3 is a valid CAS Registry Number.

Halogen-metal exchange/cyclization of iodoketones: A direct synthesis of 3-arylbenzofurans
Kraus, George A.,Schroeder, Jacob D.
, p. 2504 - 2506 (2007/10/03)
The first synthesis of benzofuran 2 was achieved in 17% overall yield in seven steps. The key step was a halogen-metal exchange/cyclization reaction. Several examples of this reaction were reported. Georg Thieme Verlag Stuttgart.
