260788-74-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 260788-74-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,0,7,8 and 8 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 260788-74:
(8*2)+(7*6)+(6*0)+(5*7)+(4*8)+(3*8)+(2*7)+(1*4)=167
167 % 10 = 7
So 260788-74-7 is a valid CAS Registry Number.

A Unified Approach to Couple Aromatic Heteronucleophiles to Azines and Pharmaceuticals

Anderson, Ryan G.,Jett, Brianna M.,McNally, Andrew

, p. 12514 - 12518 (2018)

Coupling aromatic heteronucleophiles to arenes is a common way to assemble drug-like molecules. Many methods operate via nucleophiles intercepting organometallic intermediates, via Pd-, Cu-, and Ni-catalysis, that facilitate carbon-heteroatom bond formation and a variety of protocols. We present an alternative, unified strategy where phosphonium salts can replicate the behavior of organometallic intermediates. Under a narrow set of reaction conditions, a variety of aromatic heteronucleophile classes can be coupled to pyridines and diazines that are often problematic in metal-catalyzed couplings, such as where (pseudo)halide precursors are unavailable in complex structures with multiple polar functional groups.
