Check Digit Verification of cas no

The CAS Registry Mumber 457073-91-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,7,0,7 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 457073-91:
(8*4)+(7*5)+(6*7)+(5*0)+(4*7)+(3*3)+(2*9)+(1*1)=165
165 % 10 = 5
So 457073-91-5 is a valid CAS Registry Number.

Heteroatom variants of the type 2 intramolecular Diels-Alder reaction provide an efficient method for the preparation of bridged bicyclic heterocycles. The type 2 variant of the intramolecular N-acylnitroso Diels-Alder reaction is an effective method for

Type 2 intramolecular N-acylnitroso diels-alder reaction: stereoselective synthesis of bridged bicyclic oxazinolactams.

Chow, Chun P,Shea, Kenneth J,Sparks, Steven M

, p. 2637 - 2640 (2007/10/03)

[reaction: see text] The type 2 intramolecular N-acylnitroso Diels-Alder reaction has been employed for the synthesis of substituted bridged bicyclic oxazinolactams. Upon oxidation of hydroxamic acid 6, a 3-benzylated oxazinolactam (7) was synthesized with complete diastereoselectivity. Elaboration of cycloadduct 7 liberated a cis-3,7-disubstituted azocin-2-one (9).
