72233-97-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72233-97-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,2,3 and 3 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 72233-97:
(7*7)+(6*2)+(5*2)+(4*3)+(3*3)+(2*9)+(1*7)=117
117 % 10 = 7
So 72233-97-7 is a valid CAS Registry Number.

Claisen rearrangements have been applied to 1,5-anhydro-4,6-O-benzylidene-1,2-dideoxy-D-ribo-hex-1-enitol (1).The classical procedure succeeds, but the overall process is unsatisfactory because of the low conversion to the vinyl ether intermediate.Best re
