904624-29-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 904624-29-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,4,6,2 and 4 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 904624-29:
(8*9)+(7*0)+(6*4)+(5*6)+(4*2)+(3*4)+(2*2)+(1*9)=159
159 % 10 = 9
So 904624-29-9 is a valid CAS Registry Number.

Furan-2-carbaldehydes as C1 building blocks for the synthesis of quinazolin-4(3: H)-ones via ligand-free photocatalytic C-C bond cleavage

Yu, Wenjia,Zhang, Xianwei,Qin, Bingjie,Wang, Qiyang,Ren, Xuhong,He, Xinhua

supporting information, p. 2449 - 2454 (2018/06/11)

Furan-2-carbaldehydes, as biomass-derived chemicals, are used as efficient green C1 building blocks to synthesize bioactive quinazolin-4(3H)-ones by ligand-free photocatalytic C-C bond cleavage. Notably, protection of hydroxyl, carboxyl, amide, or secondary amino groups is not required. Mechanistic studies suggest that conjugated N,O-tridentate copper complexes act as novel photoinitiators under visible light.
