Check Digit Verification of cas no

The CAS Registry Mumber 33734-07-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,7,3 and 4 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 33734-07:
(7*3)+(6*3)+(5*7)+(4*3)+(3*4)+(2*0)+(1*7)=105
105 % 10 = 5
So 33734-07-5 is a valid CAS Registry Number.

Formation of 1- and 2-Alkoxyenynes in Palladium-Catalyzed Cross-Coupling of 1- and 2-Bromoalkenyl Alkyl Ethers with Alkynes

Trostyanskaya,Shvetsov,Efimova,Kazankova,Beletskaya

, p. 946 - 950 (2007/10/03)

A preparative route to 1- and 2-alkoxyenynes is developed on the basis of stereoselective cross-coupling of 1- and 2-haloalkenyl alkyl ethers with terminal alkynes in the presence of palladium catalyst. Hydrolysis of 1- and 2-alkoxyenynes yields carbonyl derivatives containing a triple bond: substituted acetaldehyde and ketone, respectively.
