Check Digit Verification of cas no

The CAS Registry Mumber 649748-30-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,9,7,4 and 8 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 649748-30:
(8*6)+(7*4)+(6*9)+(5*7)+(4*4)+(3*8)+(2*3)+(1*0)=211
211 % 10 = 1
So 649748-30-1 is a valid CAS Registry Number.

On the reactivity of ascomycin at the binding domain. Part 1: Liberation of the tricarbonyl portion of ascomycin

Baumann, Karl,Bacher, Markus,Damont, Annelaure,H?genauer, Klemens,Steck, Andrea

, p. 10075 - 10087 (2003)

Within the binding domain, ascomycin features the unusual pattern of a masked tricarbonyl moiety, which potentially allows for high structural diversity via simple isomerisation events. Herein, methodologies, allowing the liberation of the tricarbonyl unit by blocking the 14-hydroxy group are reported.
