23417-82-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 23417-82-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,4,1 and 7 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 23417-82:
(7*2)+(6*3)+(5*4)+(4*1)+(3*7)+(2*8)+(1*2)=95
95 % 10 = 5
So 23417-82-5 is a valid CAS Registry Number.

Copper-mediated/catalyzed oxyalkylation of alkenes with alkylnitriles

Bunescu, Ala,Wang, Qian,Zhu, Jieping

, p. 14633 - 14636 (2014)

A copper-promoted oxyalkylation of alkenes with alkylnitriles has been developed. The protocol provides rapid access to phthalides (γ-lactones) or isochromanones (d-lactones) via the formation of a C(sp3)-C(sp3) and a C(sp3)-O bond with the generation of up to two quaternary carbon atoms. Mechanistic studies suggest that this reaction is initiated by the formation of the C(sp3)-C(sp3) bond rather than the C(sp3)-O bond. Catalytic conditions were subsequently developed using carboxylic acid as an internal nucleophile.
