572-45-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 572-45-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,7 and 2 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 572-45:
(5*5)+(4*7)+(3*2)+(2*4)+(1*5)=72
72 % 10 = 2
So 572-45-2 is a valid CAS Registry Number.

The C-H Activation/Bidirecting Group Strategy for Selective Direct Synthesis of Diverse 1,1′-Biisoquinolines

Kong, Xiangfei,Li, Shiqing,Lv, Hongxu,Xie, Rongrong,Ye, Xiuqing,Yu, Yu

supporting information, p. 4207 - 4212 (2020/06/24)

Multidentate ligands are highly important but difficult to access. Herein we disclose an atom- and step-economic synthesis of highly substituted 1,1′-biisoquinolines by a C-H activation/bididirecting group strategy. Through rational design of a bididirecting group to "N-OH + N-OAc", selective unsymmetrical diannulation with two different alkynes in a one-pot reaction has been achieved for the first time to access unsymmetrical biisoquinolines. Moreover, the resultant biisoquinolines show tunable photoluminescence and serve as aggregation-induced emission (AIE) systems.
