Check Digit Verification of cas no

The CAS Registry Mumber 196939-46-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,6,9,3 and 9 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 196939-46:
(8*1)+(7*9)+(6*6)+(5*9)+(4*3)+(3*9)+(2*4)+(1*6)=205
205 % 10 = 5
So 196939-46-5 is a valid CAS Registry Number.

First synthesis of cytotoxic 8,9-secokaurene diterpenoids. An enantioselective route to (-)-O-methylshikoccin and (+)- O-methylepoxyshikoccin

Paquette, Leo A.,Backhaus, Dirk,Braun, Ralf,Underiner, Ted L.,Fuchs, Klaus

, p. 9662 - 9671 (2007/10/03)

A practical route for the total synthesis of 8,9-secokaurene diterpenes is described. The central step is the 3.3]sigmatropic rearrangement of spirocyclic intermediates such as 35, 40, and 41. All three compounds must necessarily respond identically to pr
