Calculate Digit Verification of CAS Registry Number 144220-13:
(8*1)+(7*4)+(6*4)+(5*2)+(4*2)+(3*0)+(2*1)+(1*3)=83
83 % 10 = 3
So 144220-13-3 is a valid CAS Registry Number.

REACTIONS OF N,O-BIS(BROMOMAGNESIO) α-HYDROXY CARBOXAMIDES WITH CHLOROFORMIC ESTERS

Zul'karnaev, R. I.,Fedotov, A. S.,Lapkin, I. I.

, p. 316 - 321 (2007/10/02)

In the reactions of N,O-bis(bromomagnesio) α-hydroxy α-alkoxy carboxamides of the aliphatic series with chloroformic esters in boiling toluene unsaturated compounds are formed.Analogous reactions conducted at a higher temperature (boiling mesitylene) lead to the formation of reduced products.These reactions with ethyl chloroformate are faster and go with higher yields of the target product than the corresponding reactions with benzyl chloroformate.
