231617-15-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 231617-15-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,1,6,1 and 7 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 231617-15:
(8*2)+(7*3)+(6*1)+(5*6)+(4*1)+(3*7)+(2*1)+(1*5)=105
105 % 10 = 5
So 231617-15-5 is a valid CAS Registry Number.

Synthesis of 3-substituted isocoumarins via a cascade intramolecular Ullmann-type coupling-rearrangement process

Ge, Zhi-Yuan,Fei, Xiang-Dong,Tang, Ting,Zhu, Yong-Ming,Shen, Jing-Kang

experimental part, p. 5736 - 5743 (2012/08/07)

A simple and highly efficient strategy for the synthesis of 3-substituted isocoumarins through a copper(I)-catalyzed reaction of 1-(2-halophenyl)-1,3- diones has been developed. The procedure is based on a cascade copper-catalyzed intramolecular Ullmann-type C-arylation and rearrangement process. This methodology is tolerant of a wide range of substrates and applicable to library synthesis.
