Check Digit Verification of cas no

The CAS Registry Mumber 1033301-29-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,3,3,0 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1033301-29:
(9*1)+(8*0)+(7*3)+(6*3)+(5*3)+(4*0)+(3*1)+(2*2)+(1*9)=79
79 % 10 = 9
So 1033301-29-9 is a valid CAS Registry Number.

Chemical modification of plant alkaloids. 5. Spirocyclic systems based on cotarnine and barbituric acids

Krasnov,Kartsev,Khrustalev

, p. 48 - 54 (2008)

Cotarnine was reacted with barbituric acid and its N-alkylbartituric and 1,3-dimethyl-2-thio analogs under forcing conditions to produce spirocyclic systems. Adducts, further transformations of which included skeletal rearrangements (a type of T-reaction) and subsequent deamination, were formed in the first step. The reaction of N-methylcotarnine and 1,3-dimethylbarbituric acid was analogous. The properties of the spirocyclic products were studied. They were further modified at the CH-acid and aromatic moieties.
