Check Digit Verification of cas no

The CAS Registry Mumber 128442-33-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,4,4 and 2 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 128442-33:
(8*1)+(7*2)+(6*8)+(5*4)+(4*4)+(3*2)+(2*3)+(1*3)=121
121 % 10 = 1
So 128442-33-1 is a valid CAS Registry Number.

SYNTHESIS OF BOTH THE ENANTIOMERS OF HAUPTMANN'S PERIPLANONE-A AND CLARIFICATION OF THE STRUCTURE OF PERSOON'S PERIPLANONE-A

Kuwahara, Shigefumi,Mori, Kenji

, p. 8083 - 8092 (1990)

The naturally occuring (-)-enantiomer of Hauptmann's periplanone-A and its stereoisomers were synthesized.Thermal rearrangement of Hauptmann's (-)-periplanone A by GLC gave Persoon's periplanone-A, the structure of which was determined through an X-ray cr
