Check Digit Verification of cas no

The CAS Registry Mumber 51785-70-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,7,8 and 5 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 51785-70:
(7*5)+(6*1)+(5*7)+(4*8)+(3*5)+(2*7)+(1*0)=137
137 % 10 = 7
So 51785-70-7 is a valid CAS Registry Number.

Visible-Light Photocatalysis Employing Dye-Sensitized Semiconductor: Selective Aerobic Oxidation of Benzyl Ethers

Ren, Li,Yang, Ming-Meng,Tung, Chen-Ho,Wu, Li-Zhu,Cong, Huan

, p. 8134 - 8138 (2017/12/08)

The aerobic oxidation is an attractive approach toward environmentally benign synthesis of fine chemicals. In addition, dye-sensitized semiconductors are underdeveloped photocatalysts for selective organic synthesis. With the aid of catalytic eosin Y-sensitized titanium dioxide, we have developed efficient aerobic photooxidation of benzyl ethers to benzoates, featuring low cost, high atom economy, broad substrate scope, and user-friendly setup. Furthermore, preliminary mechanistic studies established that the reaction pathway likely entails a photoinduced, radical-based two-step process via an isolable peroxide intermediate.

Preparation of new acylated derivatives of L-arabinofuranose and 2-deoxy-L-erythro-pentofuranose as precursors for the synthesis of L-pentofuranosyl nucleosides

Genu-Dellac,Gosselin,Imbach

, p. 249 - 255 (2007/10/02)

1,2-Di-O-acetyl-3,5-di-O-benzoyl-L-rabinofuranose and 1-O-acetyl-3,5-di-O-benzoyl-2-deoxy-L-erythro-pentofuranose have been synthesised from L-rabinose for use in the preparation of L-pentofuranosyl nucleosides. 1,2-Di-O-acetyl-3,5-di-O-benzoyl-L-arabinof

5(S), 6(R)-5, 7-DIBENZOYLOXY-6-HYDROXYHEPTANOATE ESTER : IMPROVED SYNTHESIS OF A LEUKOTRIENE INTERMEDIATE

Marriott, D. P.,Bantick, J. R.

, p. 3657 - 3658 (2007/10/02)

The title compound, a key intermediate in the synthesis of leukotriene A4, was prepared by a convenient procedure from 2-deoxy-D-ribose.
