Check Digit Verification of cas no
The CAS Registry Mumber 303113-17-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,3,1,1 and 3 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 303113-17:
(8*3)+(7*0)+(6*3)+(5*1)+(4*1)+(3*3)+(2*1)+(1*7)=69
69 % 10 = 9
So 303113-17-9 is a valid CAS Registry Number.

Synthesis of functionalized cannabinoids
Harrington, Paul E.,Stergiades, Ioanna A.,Erickson, Joy,Makriyannis, Alexandros,Tius, Marcus A.
, p. 6576 - 6582 (2007/10/03)
An effective synthesis of tricyclic, nonclassical cannabinoids has been developed on the basis of a cation-olefin cyclization that forms the two nonaromatic rings with the desired stereochemistry in a single step.
