Check Digit Verification of cas no
The CAS Registry Mumber 130740-84-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,7,4 and 0 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 130740-84:
(8*1)+(7*3)+(6*0)+(5*7)+(4*4)+(3*0)+(2*8)+(1*4)=100
100 % 10 = 0
So 130740-84-0 is a valid CAS Registry Number.

The Total Synthesis of (+)-Norpatchoulenol: Trapping of a Non-enolizable 1,3-Diketone Intermediate with a Wittig Reagent
Liu, Hsing-Jang,Ralitsch, Milan
, p. 997 - 999 (2007/10/02)
A short total synthesis of (+)-norpatchoulenol (1) has been accomplished from (+)-camphor-10-sulphonic acid (2) involving, as a key step, the trapping of a non-enolizable 1,3-diketone intermediate with a Wittig reagent.
