613236-71-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 613236-71-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,1,3,2,3 and 6 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 613236-71:
(8*6)+(7*1)+(6*3)+(5*2)+(4*3)+(3*6)+(2*7)+(1*1)=128
128 % 10 = 8
So 613236-71-8 is a valid CAS Registry Number.

An enantioselective double Diels-Alder approach to the tetracyclic framework of colombiasin A.
Chaplin, Jason H,Edwards, Alison J,Flynn, Bernard L
, p. 1842 - 1844 (2003)
The complex tetracyclic carbon skeleton of colombiasin A is conveniently accessed through an enantioselective intermolecular Diels-Alder-sulfoxide elimination-intramolecular Diels-Alder (DA-E-IMDA) sequence.
