19484-59-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 19484-59-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,4,8 and 4 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 19484-59:
(7*1)+(6*9)+(5*4)+(4*8)+(3*4)+(2*5)+(1*9)=144
144 % 10 = 4
So 19484-59-4 is a valid CAS Registry Number.

Directed ortho metalation-cross coupling links. Carbamoyl rendition of the Baker-Venkataraman rearrangement. Regiospecific route to substituted 4- hydroxycoumarins

Kalinin, Alexey V.,Da Silva, Alcides J. M.,Lopes, Claudio C.,Lopes, Rosangela S. C.,Snieckus, Victor

, p. 4995 - 4998 (2007/10/03)

A new carbamoyl Baker-Venkataraman rearrangement (4) which allows a general synthesis of substituted 4-hydroxycoumarins 8 in 43-82% overall yields is described; the intermediate arylketones 6 are efficiently prepared (59-91% yields) via a Directed ortho Metalation - Negishi cross coupling protocol from arylcarbamates 5 and the overall sequence provides a regiospecific anionic Friedel-Crafts complement for the construction of ortho-acyl phenols and coumarins.
