Check Digit Verification of cas no

The CAS Registry Mumber 499797-43-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,9,7,9 and 7 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 499797-43:
(8*4)+(7*9)+(6*9)+(5*7)+(4*9)+(3*7)+(2*4)+(1*3)=252
252 % 10 = 2
So 499797-43-2 is a valid CAS Registry Number.

Synthesis of the 5-7-6 core of guanacastepenes. Construction of C8 quaternary carbon via the inversion of stereochemistry.

Nguyen, Truc M,Seifert, Robert J,Mowrey, Dale R,Lee, Daesung

, p. 3959 - 3962 (2002)

[formula: see text] An efficient and unique route to the 5-7-6 core of guanacatepene A (1) is described. The installation of the desired stereochemistry at the C8 position was achieved via the desymmetrization of the cyclohexadienone by reductive ring clo
