Check Digit Verification of cas no

The CAS Registry Mumber 18651-20-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,6,5 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 18651-20:
(7*1)+(6*8)+(5*6)+(4*5)+(3*1)+(2*2)+(1*0)=112
112 % 10 = 2
So 18651-20-2 is a valid CAS Registry Number.

Synthesis of Diverse Oxa-Carbocycle-Annulated Flavones Using the Combined Claisen Rearrangement and Ring-Closing Metathesis

Gogula, Thirupathi,Yerrabelly, Jayaprakash Rao

, p. 547 - 557 (2016/07/22)

A simple and efficient route for the synthesis of oxepine-, oxocine-, oxepinone-, and dioxocine-angularly annulated flavone skeletons has been developed. The combined Claisen rearrangement and the ring-closing metathesis are used as key steps for the construction of C7/C8–C6–C6tricyclic core structures.
