Check Digit Verification of cas no

The CAS Registry Mumber 1257405-22-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,4,0 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1257405-22:
(9*1)+(8*2)+(7*5)+(6*7)+(5*4)+(4*0)+(3*5)+(2*2)+(1*2)=143
143 % 10 = 3
So 1257405-22-3 is a valid CAS Registry Number.

Solvent-free synthesis of monoacylaminals from the reaction of amides and aminals as precursors in carbinolamide synthesis

Sansone, Matthew F.,Koyanagi, Takaoki,Przybyla, David E.,Nagorski, Richard W.

supporting information; experimental part, p. 6031 - 6033 (2010/11/21)

A solvent-free method of generating monoacylaminals by heating the amide and aminal starting materials in the presence of one another has been developed. Yields were generally between 45% and 65% with the monoacylaminal being isolated, needing no further purification after drying under high vacuum.
