Check Digit Verification of cas no

The CAS Registry Mumber 135068-50-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,0,6 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 135068-50:
(8*1)+(7*3)+(6*5)+(5*0)+(4*6)+(3*8)+(2*5)+(1*0)=117
117 % 10 = 7
So 135068-50-7 is a valid CAS Registry Number.

Amide Acetal Claisen Rearrangement in the Synthesis of Mesembrane Alkaloids

Bauermeister, Sieglinde,Gouws, Izebrandt D.,Strauss, Heinrich F.,Venter, Elise M. M.

, p. 561 - 565 (2007/10/02)

The synthesis of primary and secondary allylic alcohols (differing in the degree of steric hindrance) and of amide acetals (achiral and chiral) is reported.These compounds were used as substrates in the amide acetal Claisen rearrangement, and the effect of Lewis acids on the stereoselectivity of the reaction was studied.The rearrangement products have been applied to the synthesis of the mesembrane alkaloids (-)-mesembranone, rac-O-methyljourbertiamine and joubertiamine.
