Check Digit Verification of cas no

The CAS Registry Mumber 740834-75-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,0,8,3 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 740834-75:
(8*7)+(7*4)+(6*0)+(5*8)+(4*3)+(3*4)+(2*7)+(1*5)=167
167 % 10 = 7
So 740834-75-7 is a valid CAS Registry Number.

On the reactivity of ascomycin at the binding domain. Part 2: Hydroxide mediated rearrangement reactions

Baumann, Karl,Bacher, Markus,Steck, Andrea,Wagner, Trixie

, p. 5965 - 5981 (2007/10/03)

The natural product ascomycin represents a highly functionalised 23-membered macrocycle with a polyketide backbone. 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, highly stereoselective, hydroxide mediated rearrangement reactions at the binding domain are reported.
