Check Digit Verification of cas no

The CAS Registry Mumber 330998-91-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,0,9,9 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 330998-91:
(8*3)+(7*3)+(6*0)+(5*9)+(4*9)+(3*8)+(2*9)+(1*1)=169
169 % 10 = 9
So 330998-91-9 is a valid CAS Registry Number.

A short synthesis of Mniopetal F?

Jauch, Johann

, p. 473 - 476 (2007/10/03)

The first total synthesis of Mniopetal F in fourteen steps is reported. Key steps are a new and highly diastereoselective lithium phenylselenide-induced Baylis-Hillman reaction with Feringa's butenolide, an endo-selective intramolecular Diels-Alder reaction (IMDA), inversion of a highly hindered secondary alcohol and a new variant of the Parikh-Doering oxidation.
