Check Digit Verification of cas no

The CAS Registry Mumber 174291-07-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,4,2,9 and 1 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 174291-07:
(8*1)+(7*7)+(6*4)+(5*2)+(4*9)+(3*1)+(2*0)+(1*7)=137
137 % 10 = 7
So 174291-07-7 is a valid CAS Registry Number.

Staurosporine and ent-staurosporine: The first total syntheses, prospects for a regioselective approach, and activity profiles

Link,Raghavan, Subharekha,Gallant, Michel,Danishefsky, Samuel J.,Chou,Ballas, Lawrence M.

, p. 2825 - 2842 (2007/10/03)

The total syntheses of staurosporine and ent-staurosporine have been achieved. Both glycosidic bonds were built from glycal precursors. The first was constructed by intermolecular coupling of an indole anion with a 1,2-anhydrosugar derived from an endo-glycal by direct epoxidation. The second bond was assembled from an exo-glycal by intramolecular iodoglycosylation.
