Check Digit Verification of cas no

The CAS Registry Mumber 879547-42-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,9,5,4 and 7 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 879547-42:
(8*8)+(7*7)+(6*9)+(5*5)+(4*4)+(3*7)+(2*4)+(1*2)=239
239 % 10 = 9
So 879547-42-9 is a valid CAS Registry Number.

Metal-free tandem reaction in water: An efficient and regioselective synthesis of 3-hydroxyisoindolin-1-ones

Zhou, Yu,Zhai, Yun,Li, Jian,Ye, Deju,Jiang, Hualiang,Liu, Hong

experimental part, p. 1397 - 1404 (2010/09/16)

A mild and effective method was developed for the construction of heterocyclic building blocks 3-hydroxyisoindolin-1-ones via a metal-free tandem transformation with excellent regioselectivity. Significantly, the strategy presents an atom-economical and environmentally friendly transformation, in which two new C-N bonds and one C-O bond are formed in water from two simple starting materials. Moreover, a broad spectrum of substrates can participate in the process effectively to produce the desired products in good yields.
