Check Digit Verification of cas no
The CAS Registry Mumber 426210-81-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,6,2,1 and 0 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 426210-81:
(8*4)+(7*2)+(6*6)+(5*2)+(4*1)+(3*0)+(2*8)+(1*1)=113
113 % 10 = 3
So 426210-81-3 is a valid CAS Registry Number.

As long as 50 years ago theoretical calculations predicted that Moebius annulenes with only one π surface and one edge would exhibit peculiar electronic properties and violate the Hueckel rules. Numerous synthetic attempts notwithstanding, the first singly twisted Moebius annulene was not prepared until 2003. Here we present a general, rational strategy to synthesize triply or even more highly twisted cyclic π systems. We apply this strategy to the preparation of a triply twisted [24]dehydroannulene, the structure of which was confirmed by X-ray analysis. Our strategy is based on the topological transformation of 'twist' into 'writhe'. The advantage is twofold: the product exhibits a lower degree of strain and precursors can be designed that inherently include the writhe, which, after cyclization, ends up in the Moebius product. With our strategy, triply twisted systems are easier to prepare than their singly twisted counterparts.
