Check Digit Verification of cas no

The CAS Registry Mumber 1011287-43-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,1,2,8 and 7 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1011287-43:
(9*1)+(8*0)+(7*1)+(6*1)+(5*2)+(4*8)+(3*7)+(2*4)+(1*3)=96
96 % 10 = 6
So 1011287-43-6 is a valid CAS Registry Number.

Synthesis of (+)-zerumin B using a regioselective singlet oxygen furan oxidation

Margaros, Ioannis,Vassilikogiannakis, Georgios

, p. 2021 - 2023 (2008)

(Chemical Equation Presented) A short and efficient synthesis of the antitumor diterpenoid (+)-zerumin B has been accomplished starting from (+)-sclareolide. At the heart of the synthetic strategy lies the regioselective formation of the α-substituted γ-hydroxybutenolide moiety of zerumin B. This was achieved by means of a [1,4] O→C triisopropylsilyl migration followed by singlet oxygen (1O2) oxidation of the resulting 2-triisopropylsilyl-3-(α-hydroxy)alkylfuran.
