Check Digit Verification of cas no

The CAS Registry Mumber 934389-54-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,4,3,8 and 9 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 934389-54:
(8*9)+(7*3)+(6*4)+(5*3)+(4*8)+(3*9)+(2*5)+(1*4)=205
205 % 10 = 5
So 934389-54-5 is a valid CAS Registry Number.

Synthesis of N-heterocyclic compounds via ene-yne metathesis reactions

Groaz, Elisabetta,Banti, Donatella,North, Michael

, p. 204 - 218 (2008)

Propargylamino and allylamino derivatives of cyclohexene and norbornene were subjected to tandem metathesis reactions with first and second generation Grubbs' catalysts 1 and 2. Results show that the method is compatible with suitably protected nitrogen-containing compounds. Cyclohexenes gave intriguing results in terms of the possibility to perform ring rearrangement metathesis (RRM) reactions, showing a difference with the analogous allyl and propargyl ether substrates.
