Check Digit Verification of cas no

The CAS Registry Mumber 634181-80-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,4,1,8 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 634181-80:
(8*6)+(7*3)+(6*4)+(5*1)+(4*8)+(3*1)+(2*8)+(1*0)=149
149 % 10 = 9
So 634181-80-9 is a valid CAS Registry Number.

Synthesis of 3-deoxy-3,3-difluoro-d-ribohexose from gem-difluorohomoallyl alcohol

Xu, Xiu-Hua,You, Zheng-Wei,Zhang, Xingang,Qing, Feng-Ling

, p. 535 - 539 (2007/12/27)

A novel synthetic route to 3-deoxy-3,3-difluoro-d-ribohexose 1 has been developed. Dihydroxidation of gem-difluorohomoallyl alcohol followed by several steps of protection and deprotection gave key intermediate 9. Oxidation of 1,5-diol 9 with 2 equiv. tri

Synthesis of L- and D-β-3′-deoxy-3′,3′- difluoronucleosides

Xu, Xiu-Hua,Qiu, Xiao-Long,Zhang, Xingang,Qing, Feng-Ling

, p. 2820 - 2824 (2007/10/03)

Both L- and D-β-3′-deoxy-3′,3′-difluoronucleosides were synthesized starting from the key intermediate difluorohomoallyl alcohol 11. Deoxo-Fluor was accidentally found to be efficient in reversing the hydroxyl configuration of 34, and the desired product

3-Deoxy-3,3-difluoro-D-arabinofuranose: First Stereoselective Synthesis and Application in Preparation of gem-Difluorinated Sugar Nucleosides

Zhang, Xingang,Xia, Hairong,Dong, XiCheng,Jin, Jing,Meng, Wei-Dong,Qing, Feng-Ling

, p. 9026 - 9033 (2007/10/03)

The design and synthesis of gem-difluorinated sugar nucleosides were described. The key intermediate, 3-deoxy-3,3-difluoro-D-arabinofuranose 9, was first stereoselectively prepared from the chiral gem-difluorohomoallyl alcohol 12. The kinetic formation of
