Check Digit Verification of cas no

The CAS Registry Mumber 620937-43-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,0,9,3 and 7 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 620937-43:
(8*6)+(7*2)+(6*0)+(5*9)+(4*3)+(3*7)+(2*4)+(1*3)=151
151 % 10 = 1
So 620937-43-1 is a valid CAS Registry Number.

Silver acetate-assisted formation of amides from acyl chlorides

Leggio,Belsito,Di Gioia,Leotta,Romio,Siciliano,Liguori

, p. 199 - 202 (2014)

A mild method for the aminolysis of carboxylic acid chlorides to give amides is disclosed. Reactions are carried out in the presence of silver acetate in non-aqueous environments under heterogeneous phase conditions. Amides are easily recovered in very good to excellent yields and without racemization. The approach is successful in forming peptide bonds starting from N-(4-nitrobenzenesulfonyl)-amino acid chlorides and allows the formation of dipeptides also when N-methylated amino acid derivatives are used.
