107643-12-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 107643-12-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,6,4 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 107643-12:
(8*1)+(7*0)+(6*7)+(5*6)+(4*4)+(3*3)+(2*1)+(1*2)=109
109 % 10 = 9
So 107643-12-9 is a valid CAS Registry Number.

Some Observations on the Brunner Reaction
Wolff, Jens,Taddei, Maurizio
, p. 4267 - 4272 (2007/10/02)
Elucidation of the stereochemical course of the Brunner reaction is described.A slight modification in the procedure gives better yields and seems very promising for a more general application of this reaction.
