Check Digit Verification of cas no

The CAS Registry Mumber 82228-91-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,2,2 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 82228-91:
(7*8)+(6*2)+(5*2)+(4*2)+(3*8)+(2*9)+(1*1)=129
129 % 10 = 9
So 82228-91-9 is a valid CAS Registry Number.

Mild and Simple Biomimetic Conversion of Amines to Carbonyl Compounds

Buckley, Thomas F.,Rapoport, Henry

, p. 4446 - 4450 (2007/10/02)

4-Formyl-1-methylpyridinium benzenesulfonate is a convenient reagent for the chemical modification of primary amines to aldehydes and ketones.This method mimics the biological process for transamination reactions with pyridoxal (vitamin b6).As in that process, it involves imine formation, prototropic rearrangement, and hydrolysis.The conditions are extremely mild and are compatible with a large variety of sensitive functional groups.This process provides a simple and a efficient alternative to the somewhat harsher procedures generally employed for such transformations.
