Check Digit Verification of cas no
The CAS Registry Mumber 64341-49-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,3,4 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 64341-49:
(7*6)+(6*4)+(5*3)+(4*4)+(3*1)+(2*4)+(1*9)=117
117 % 10 = 7
So 64341-49-7 is a valid CAS Registry Number.

Investigation of 1-bromo-3-buten-2-one as building block in organic synthesis

1-Bromo-3-buten-2-one is investigated as a building block for organic synthesis. Reduction to the corresponding alcohol works best with lithium aluminium hydride, reaction with primary amines gives 5-membered-aza-heterocycles in moderate yields and reaction with activated methylene compounds to form 5-membered-carbocycles gave unsatisfactory yields when a one-pot-procedure was used. The first step of a stepwise protocol, a Michael addition, is discussed.
