5111-13-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5111-13-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,1 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5111-13:
(6*5)+(5*1)+(4*1)+(3*1)+(2*1)+(1*3)=47
47 % 10 = 7
So 5111-13-7 is a valid CAS Registry Number.

Synthesis of 1,3,4,6-Tetra-O-acetyl-l-gulose

Che, Rui,Liu, Xingui,Lu, Wei

, p. 237 - 241 (2017/03/05)

A novel, practical and concise synthesis of 1,3,4,6-tetra-O-acetyl-l-gulose is described, using d-glucuronolactone as the starting material and other inexpensive and readily available agents (22% overall yield in 9 steps). With this method, the synthesis of l-gulose and the tumor-targeting disaccharide of BLMs can be more efficient and convenient.

An efficient and straightforward synthetic process to an amino sugar analogue, furanodictine B

Matsuura, Daisuke,Nojiri, Tomoko,Suzuki, Yuji,Takabe, Kunihiko,Yoda, Hidemi

, p. 287 - 288 (2007/10/03)

A convenient and practical strategy for the construction of a natural amino sugar analogue, furanodictine B, isolated from the multicellular fruit body has been developed in an optically active form. The synthetic process is based on readily accessible and stereodefmed manipulation of the highly functionalized bicyclic derivative incorporating the glucuronolactone-derived skeleton.
