71475-22-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 71475-22-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,4,7 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 71475-22:
(7*7)+(6*1)+(5*4)+(4*7)+(3*5)+(2*2)+(1*2)=124
124 % 10 = 4
So 71475-22-4 is a valid CAS Registry Number.

Intramolecular and intermolecular Schmidt reactions of alkyl azides with aldehydes
Lee, Huey-Lih,Aubé, Jeffrey
, p. 9007 - 9015 (2007)
Despite recent advances in the use of alkyl azides in ring expansion reactions of ketones, there has been little work done on the corresponding chemistry of aldehydes. In the present study, the Lewis acid-promoted reactions of alkyl azides with aldehydes
