29976-84-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 29976-84-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,9,7 and 6 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 29976-84:
(7*2)+(6*9)+(5*9)+(4*7)+(3*6)+(2*8)+(1*4)=179
179 % 10 = 9
So 29976-84-9 is a valid CAS Registry Number.

Transition-Metal-Free Photoinduced Intramolecular Annulation of 2,3-Di(hetero)arylchromen-4-one

Han, Jie,Wang, Tao,Liang, Yong,Li, Ying,Li, Chenchen,Wang, Rui,Feng, Siqi,Zhang, Zunting

supporting information, p. 3552 - 3555 (2017/07/17)

An efficient transition-metal-free photoinduced intracyclization of 4H-chromen-4-ones in EtOH-H2O (7:1, v/v) at ambient temperature for the construction of complicated fused-ring heteroaromatics is established. The reaction proceeds smoothly without requiring any catalysts/additives.

One pot synthesis of 1-(2-hydroxyphenyl)-3-phenylpropane-1,3-diones by modified Baker-Venkataraman transformation using microwave irradiation
