264143-27-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 264143-27-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,4,1,4 and 3 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 264143-27:
(8*2)+(7*6)+(6*4)+(5*1)+(4*4)+(3*3)+(2*2)+(1*7)=123
123 % 10 = 3
So 264143-27-3 is a valid CAS Registry Number.

Further studies on nickel-promoted or -catalyzed cyclization of 1,3- diene and a tethered carbonyl group
Sato,Takimoto,Mori
, p. 1624 - 1634 (2007/10/03)
A nickel-promoted intramolecular cyclization of 1,3-diene with the tethered carbonyl group was developed using the catalyst generated by reduction of Ni(acac)2 with DIBAL-H in the presence of PPh3. It was found that the addition of 1
