Check Digit Verification of cas no
The CAS Registry Mumber 5813-90-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,1 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5813-90:
(6*5)+(5*8)+(4*1)+(3*3)+(2*9)+(1*0)=101
101 % 10 = 1
So 5813-90-1 is a valid CAS Registry Number.

Amidation of esters assisted by Mg(OCH3)2 or CaCl2
Bundesmann, Mark W.,Coffey, Steven B.,Wright, Stephen W.
experimental part, p. 3879 - 3882 (2010/08/19)
Magnesium methoxide (Mg(OCH3)2) and calcium chloride have been shown to facilitate the direct aminolysis of esters by ammonia to primary amides. Methyl, ethyl, isopropyl, and tert-butyl esters were converted to the corresponding carboxamides in good yields. Reactions have been run on a larger scale and without the safety liability inherent in the use of magnesium nitride (Mg3N2). Ammonium chloride and amine hydrochlorides have been used successfully in the place of ammonia with magnesium methoxide.
