Check Digit Verification of cas no

The CAS Registry Mumber 140705-90-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,7,0 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 140705-90:
(8*1)+(7*4)+(6*0)+(5*7)+(4*0)+(3*5)+(2*9)+(1*0)=104
104 % 10 = 4
So 140705-90-4 is a valid CAS Registry Number.

Novel rearrangements of chiral 3-oxazolidinylazetidin-2-ones

Ojima,Pei

, p. 887 - 890 (1992)

Reaction of a 3-oxazolininyl-4-hydroxymethylazetidin-2-one with excess NaOMe in refluxing methanol gives the corresponding 4-oxa-1,8-diazabicyclo[4.3.0]nonan-5,9-dione stereospecifically in nearly quantitative yield via a novel skeletal rearrangement, whi
