Check Digit Verification of cas no

The CAS Registry Mumber 70086-90-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,0,8 and 6 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 70086-90:
(7*7)+(6*0)+(5*0)+(4*8)+(3*6)+(2*9)+(1*0)=117
117 % 10 = 7
So 70086-90-7 is a valid CAS Registry Number.

Cross-metathesis of methyl 10-undecenoate with dimethyl maleate: An efficient protocol with nearly quantitative yields

Behr,Toepell,Harmuth

, p. 16320 - 16326 (2014/05/06)

In this cross metathesis of the renewable raw material methyl 10-undecenoate with dimethyl maleate, an α,ω-difunctional product was produced. Detailed optimizations led to nearly quantitative yields of the desired product. The cross metathesis of methyl 10-undecenoate with methyl acrylate yielded high conversions of the substrate. The product was accessed under mild reaction conditions with the use of a small amount of a commercially available homogeneous ruthenium catalyst. The in situ synthesis of dimethyl maleate from maleic anhydride was also possible in this reaction system. This journal is the Partner Organisations 2014.
