774-51-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 774-51-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,7 and 4 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 774-51:
(5*7)+(4*7)+(3*4)+(2*5)+(1*1)=86
86 % 10 = 6
So 774-51-6 is a valid CAS Registry Number.

A Versatile Route to Unstable Diazo Compounds via Oxadiazolines and their Use in Aryl–Alkyl Cross-Coupling Reactions

Greb, Andreas,Poh, Jian-Siang,Greed, Stephanie,Battilocchio, Claudio,Pasau, Patrick,Blakemore, David C.,Ley, Steven V.

, p. 16602 - 16605 (2017/12/13)

Coupling of readily available boronic acids and diazo compounds has emerged recently as a powerful metal-free carbon–carbon bond forming method. However, the difficulty in forming the unstable diazo compound partner in a mild fashion has hitherto limited their general use and the scope of the transformation. Here, we report the application of oxadiazolines as precursors for the generation of an unstable family of diazo compounds using flow UV photolysis and their first use in divergent protodeboronative and oxidative C(sp2)?C(sp3) cross-coupling processes, with excellent functional-group tolerance.
