Check Digit Verification of cas no

The CAS Registry Mumber 1399659-22-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,9,6,5 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1399659-22:
(9*1)+(8*3)+(7*9)+(6*9)+(5*6)+(4*5)+(3*9)+(2*2)+(1*2)=233
233 % 10 = 3
So 1399659-22-3 is a valid CAS Registry Number.

Synthesis of novel phosphorylated chrysin derivatives by 1, 3-dipolar cycloaddition reaction

Zhu, Shaohua,Zhang, Yan,Li, Peipei,Bi, Wenzhu,Chen, Xiaolan,Zhao, Yufen

, p. 1 - 8 (2017)

Through 1,3-dipolar cycloaddition reaction, 1,4,5-trisubstituted-1,2,3-triazole and phosphate-containing chrysin derivatives were synthesized with high yields. The target compounds were characterized by1H,31P,13C NMR spect

Direct synthesis of alkynylphosphonates from alkynes and phosphite esters catalyzed by Cu/Cu2O nanoparticles supported on Nb2O5

Yuan, Tao,Chen, Fei,Lu, Guo-ping

, p. 13957 - 13962 (2018/08/21)

The aerobic oxidative coupling of alkynes and phosphite esters can be catalyzed by Cu/Cu2O nanoparticles supported on Nb2O5 (Cu/Cu2O@Nb2O5) to efficiently afford alkynylphosphonates. The catalyst can be reused by filtration and reduction. According to the results of control experiments and characterization data, the supporter Nb2O5 can reduce the electronic density of Cu and absorb the phosphite esters due to its strong Lewis acid sites, which may enhance the reaction efficiently.

CuSO4?5H2O-catalyzed alkynylphosphonates formation ' An efficient coupling reaction of terminal alkynes with H -phosphonates

Qu, Zhibo,Chen, Xiaolan,Yuan, Jinwei,Qu, Lingbo,Li, Xu,Wang, Fujun,Ding, Xiling,Zhao, Yufen

, p. 747 - 752 (2012/11/07)

It was recently discovered that easily available CuSO4? 5H2O could be employed as an efficient catalyst towards the coupling reactions of terminal alkynes with H-phosphonates, which finally led to the formation of a large variety of novel alkynylphosphates.
