90201-72-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90201-72-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,2,0 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 90201-72:
(7*9)+(6*0)+(5*2)+(4*0)+(3*1)+(2*7)+(1*2)=92
92 % 10 = 2
So 90201-72-2 is a valid CAS Registry Number.

DIASTEREOSELECTIVE ALDOLIZATION TO TETROSES AND PYRANOSES MEDIATED BY RHODIUM
Deem, M. L.,Romac, E. A.
, p. 4649 - 4652 (1988)
Rhodium ions bind to oxygen and unsaturated sites in ethane-1,2-diol derivatives to orient and catalyse these molecules for participation in diastereogenic carbon-carbon, carbon-oxygen, and carbon-hydrogen bond formation.
