Check Digit Verification of cas no

The CAS Registry Mumber 105249-97-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,2,4 and 9 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 105249-97:
(8*1)+(7*0)+(6*5)+(5*2)+(4*4)+(3*9)+(2*9)+(1*7)=116
116 % 10 = 6
So 105249-97-6 is a valid CAS Registry Number.

Lithium/DTBB-induced reduction of N-alkoxyamides and acyl azides

Yus, Miguel,Radivoy, Gabriel,Alonso, Francisco

, p. 914 - 918 (2007/10/03)

A series of N-alkoxyamides and N-methoxy-N-methylamides (Weinreb amides) have been subjected to dealkoxylation by reductive cleavage of the N-O bond with lithium powder and a catalytic amount of DTBB (10 mol%) at room temperature, leading to the corresponding amides. When the reaction is performed under reflux conditions, the corresponding alkanes, resulting from a formal deaminocarbonylation process, are obtained. This methodology applied to acyl azides furnished the corresponding primary amides.
