It possesses a sweet floral odor and is sparingly soluble in water but soluble in organic solvents.
Check Digit Verification of cas no
The CAS Registry Mumber 2671-84-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,7 and 1 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2671-84:
(6*2)+(5*6)+(4*7)+(3*1)+(2*8)+(1*4)=93
93 % 10 = 3
So 2671-84-3 is a valid CAS Registry Number.

Facile preparation of 5-alkyl-1-aryltetrazoles with arenes, acyl chlorides, hydroxylamine, and diphenylphosphoryl azide

, p. 1816 - 1830 (2020/11/19)
Successive treatment of arenes with acyl chlorides and AlCl3, the addition of water and removal of solvent, the reaction with NH2OH?HCl and K2CO3, and the reaction with diphenylphosphoryl azide and DBU under warming conditions gave the corresponding 5-alkyl-1-aryltetrazoles efficiently in good to moderate yields. The present method is one-pot transformation of arenes into 5-alkyl-1-aryltetrazoles using the Friedel-Crafts acylation and the Beckmann rearrangement under transition-metal-free conditions.
