433728-83-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 433728-83-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,3,7,2 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 433728-83:
(8*4)+(7*3)+(6*3)+(5*7)+(4*2)+(3*8)+(2*8)+(1*3)=157
157 % 10 = 7
So 433728-83-7 is a valid CAS Registry Number.

The shortest route to chiral ditosylmethylamine
Faucher, Nicolas,Cintrat, Jean-Christophe,Berthault, Patrick,Rousseau, Bernard
, p. 497 - 498 (2007/10/03)
Only non-enzymatic transformations were used to synthesize chiral N,N-ditosylmethylamine (see picture). This facile and convenient synthesis allows access to both enantiomers of the methyl group in an enantiomeric ration of 83:17.
