Check Digit Verification of cas no

The CAS Registry Mumber 1033757-01-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,3,7,5 and 7 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1033757-01:
(9*1)+(8*0)+(7*3)+(6*3)+(5*7)+(4*5)+(3*7)+(2*0)+(1*1)=125
125 % 10 = 5
So 1033757-01-5 is a valid CAS Registry Number.

Evolution of natural product scaffolds by acyl- and arylnitroso hetero-diels-alder reactions: New chemistry on pipeline

Krchnak, Viktor,Waring, Katherine R.,Noll, Bruce C.,Moellmann, Ute,Dahse, Hans-Martin,Miller, Marvin J.

, p. 4559 - 4567 (2008/12/20)

(Chemical Equation Presented) Piperine, a natural product containing a conjugated diene, was reacted with polymer-supported acyl- and arylnitroso dienophiles. The reactions with arylnitroso dienophiles were also carried out in solution. The oxazine rings formed by the corresponding hetero-Diels-Alder reactions were further transformed and novel acyclic as well as heterocyclic derivatives including pyrroles and quinoxalinones were prepared.
