Check Digit Verification of cas no

The CAS Registry Mumber 139269-65-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,2,6 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 139269-65:
(8*1)+(7*3)+(6*9)+(5*2)+(4*6)+(3*9)+(2*6)+(1*5)=161
161 % 10 = 1
So 139269-65-1 is a valid CAS Registry Number.

Acetylcyclopropane as a Five-Carbon Building Block in the Synthesis of some Acetogenin Insect Pheromones

Moiseenkov, Alexander M.,Czeskis, Boris A.,Ivanova, Natalya M.,Nefedov, Oleg M.

, p. 2639 - 2649 (2007/10/02)

Interaction of deprotonated acetylcyclopropane cyclohexylimine with several aliphatic alkyl halides, epoxides, and aldehydes efficiently gave the corresponding cyclopropyl ketones.Some of the respectible alcohols were rearranged in a highly stereoselective manner under the action of trimethylsilyl bromide in the presence of zinc bromide into the corresponding linear (E)-homoallyl bromides.The latter were used, in turn, as key intermediates in concise syntheses of thirteen terminally functionalized straight-chain oligoolefins which are known to constitute acetogenin pheromonal components for more than 65 species of lepidopteran insects.
