5531-09-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5531-09-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,3 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5531-09:
(6*5)+(5*5)+(4*3)+(3*1)+(2*0)+(1*9)=79
79 % 10 = 9
So 5531-09-9 is a valid CAS Registry Number.

ACIDIC DYSTROGLYCAN OLIGOSACCHARIDE COMPOUND AND METHOD FOR MAKING SAME

-

Paragraph 0074; 00113; 00130, (2019/07/20)

A synthetic dystroglycan oligosaccharide comprising Formula (I) wherein a repeating disaccharide motif consists of Glucuronic Acid (ClcA) and Xylose (Xyl) having a defined glycosyl connection GlcA-β-(1→3)-Xyl-α-(1→3)-GlcA; wherein either end of the synthetic dystroglycan oligosaccharide is conjugatable with chemical or biological vehicle or support; wherein the non-reducing terminal (II) is conjugatable with any oligosaccharides or groups that can modify a hydroxyl functionality; and wherein the reducing terminal is conjugatable with any tags, oligosaccharides or anything that can modify a hydroxyl functionality.

Total synthesis of viscumneoside III of Viscum coloratum

Zou, Lei,Zhang, Zixue,Chen, Xiaowen,Chen, Hua,Zhang, Yi,Li, Jianqi,Liu, Yu

, p. 2376 - 2382 (2018/04/06)

The first total synthesis of viscumneoside III, a promising anti-angina pectoris dihydroflavone O-glycoside isolated from Viscum coloratum was described here. Trichloroaceti-midate was employed as the apiofuranosyl donor to construct the key building block of homoeriodictyol-7-O-β-D-apiosyl-(1 → 2)-β-D-glycoside (1). The longest linear sequence (from 2 to 1) in the synthetic route required thirteen steps and afforded the final product 1 with an overall yield of 6.3%.
