Check Digit Verification of cas no
The CAS Registry Mumber 104504-63-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,5,0 and 4 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 104504-63:
(8*1)+(7*0)+(6*4)+(5*5)+(4*0)+(3*4)+(2*6)+(1*3)=84
84 % 10 = 4
So 104504-63-4 is a valid CAS Registry Number.

, p. 809 - 814 (2007/10/02)
The thermolysis of 5-acyltriazolines 1, 2, 3 (X=COR', Y=CO2Me) was studied.Instead of the expected aziridines, enamides 5 to 8 were obtained by an unusual acyl migration.It has been shown that the reaction is intramolecular and proceeds via a 1,2 followed
