Check Digit Verification of cas no

The CAS Registry Mumber 138783-72-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,7,8 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 138783-72:
(8*1)+(7*3)+(6*8)+(5*7)+(4*8)+(3*3)+(2*7)+(1*2)=169
169 % 10 = 9
So 138783-72-9 is a valid CAS Registry Number.

13C magnetic resonance studies. 144.1 An examination of β-enolization in the bicyclo[3.3.1]-and [3.2.2]nonan-2-one system

Muir, David J.,Stothers

, p. 1099 - 1105 (1993)

While 3, 3-dimethylbicyclo[3.3. l]nonan-2-one (5) is stable under strongly basic conditions (/-BuCT//-BuOH/185°C), its isomer, 3, 3-dimethylbicyclo[3. 2.2]nonan-2-one (6), is slowly transformed to 5. Similarly, 3, 3-dimethylbicyclo-[3.2.2]non-6-en-2-one (
