5757-86-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5757-86-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,5 and 7 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 5757-86:
(6*5)+(5*7)+(4*5)+(3*7)+(2*8)+(1*6)=128
128 % 10 = 8
So 5757-86-8 is a valid CAS Registry Number.

Synthesis of isoquinolines via Rh(III)-catalyzed C-H activation using hydrazone as a new oxidizing directing group

Chuang, Sheng-Chieh,Gandeepan, Parthasarathy,Cheng, Chien-Hong

supporting information, p. 5750 - 5753 (2013/12/04)

An efficient and mechanistically interesting method for the synthesis of highly substituted isoquinolines by a Rh(III)-catalyzed hydrazone directed ortho C-H bond activation and annulation without an external oxidant is described. This reaction is accomplished via a C-C and C-N bond formation along with N-N bond cleavage.
