Check Digit Verification of cas no
The CAS Registry Mumber 424-54-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 4 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 424-54:
(5*4)+(4*2)+(3*4)+(2*5)+(1*4)=54
54 % 10 = 4
So 424-54-4 is a valid CAS Registry Number.

N-acylbenzotriazoles: Neutral acylating reagents for the preparation of primary, secondary, and tertiary amides
Katritzky,He,Suzuki
, p. 8210 - 8213 (2007/10/03)
Readily available N-acylbenzotriazoles 2a-q efficiently acylate aqueous ammonia and primary and secondary amines to give primary, secondary, and tertiary amides in good to excellent yields. The wide applicability of the procedure is illustrated by the preparation of (i) α-hydroxyamides from α-hydroxy acids and of (ii) perfluoroalkylated amides.
