Check Digit Verification of cas no

The CAS Registry Mumber 503303-05-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,3,3,0 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 503303-05:
(8*5)+(7*0)+(6*3)+(5*3)+(4*0)+(3*3)+(2*0)+(1*5)=87
87 % 10 = 7
So 503303-05-7 is a valid CAS Registry Number.

Aflexible synthesis of cyclopentitol derivatives based on ring-closing metathesis of carbohydrate-derived 1,6-dienes

Ovaa, Huib,Lastdrager, Bas,Codee, Jeroen D. C.,Van der Marel, Gijs A.,Overkleeft, Herman S.,Van Boom, Jacques H.

, p. 2370 - 2377 (2002)

Four partially protected stereoisomeric cyclopentenetriols 5, 10, 15 and 21 have been prepared by ring-closing metathesis of carbohydrate-derived 1,6-dienes. The presence of a differentiated allylic alcohol in the cyclopentenetriols allows a variety of synthetic transformations, underlining the synthetic use of the prepared cyclopentenetriol derivatives as chiral building blocks.
