Check Digit Verification of cas no
The CAS Registry Mumber 33665-24-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,6,6 and 5 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 33665-24:
(7*3)+(6*3)+(5*6)+(4*6)+(3*5)+(2*2)+(1*4)=116
116 % 10 = 6
So 33665-24-6 is a valid CAS Registry Number.

An unusual Mannich type reaction of tertiary aromatic amines in aqueous micelles
Kumar, Atul,Maurya, Ram Awatar
, p. 5471 - 5474 (2008/12/21)
An efficient, unusual Mannich type reaction of tertiary aromatic amines, formaldehyde and 1,3-dicarbonyl compounds is described in aqueous micelles catalyzed by boric acid to afford dialkylaminoarylated 1,3-dicarbonyls. In this unusual Mannich type reacti
