139454-83-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139454-83-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,4,5 and 4 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 139454-83:
(8*1)+(7*3)+(6*9)+(5*4)+(4*5)+(3*4)+(2*8)+(1*3)=154
154 % 10 = 4
So 139454-83-4 is a valid CAS Registry Number.

REACTIONS OF 1-AZA-1,3-ENYNES WITH ALIPHATIC AZIDES
Khramchikhin, A. V.,Stadnichuk, M. D.
, p. 1864 - 1869 (2007/10/02)
Benzyl and ethoxycarbonylmethyl azides have been shown to add chemospecifically and regioselectively to the triple bond in 1-aza-1,3-alkenynes R1CCCH=NR2 to give aldimines of the corresponding triazolecarbaldehydes.The selectivity
