Check Digit Verification of cas no

The CAS Registry Mumber 200491-14-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,4,9 and 1 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 200491-14:
(8*2)+(7*0)+(6*0)+(5*4)+(4*9)+(3*1)+(2*1)+(1*4)=81
81 % 10 = 1
So 200491-14-1 is a valid CAS Registry Number.

Synthesis of amino sugars through a highly diastereoselective dipolar cycloaddition. Enantioselective synthesis of the carbohydrate segment of Sch 38516

Xu, Zhongmin,Johannes, Charles W.,La, Daniel S.,Hofilena, Gloria E.,Hoveyda, Amir H.

, p. 16377 - 16390 (2007/10/03)

A concise and stereoselective route for the synthesis of the carbohydrate moiety of the antifungal agent Sch 38516 is described. The synthesis scheme includes a dipolar cycloaddition, which is rendered diastereoselective through the use of a readily available and easily removable chiral auxiliary.
