storage
Dodecylbenzenesulfonyl azide is the safest of the usual are nesulfonyl azides (tosyl azide, etc.) employed in diazo-transfer processes;appropriate care should be taken,as with all azides. Use in a fume hood.
Purification Methods
elution through short column containing silica gel G with methylene chloride-hexane (1:4) as eluant.
Check Digit Verification of cas no
The CAS Registry Mumber 79791-38-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,7,9 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 79791-38:
(7*7)+(6*9)+(5*7)+(4*9)+(3*1)+(2*3)+(1*8)=191
191 % 10 = 1
So 79791-38-1 is a valid CAS Registry Number.
