Check Digit Verification of cas no

The CAS Registry Mumber 143377-01-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,3,7 and 7 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 143377-01:
(8*1)+(7*4)+(6*3)+(5*3)+(4*7)+(3*7)+(2*0)+(1*1)=119
119 % 10 = 9
So 143377-01-9 is a valid CAS Registry Number.

Olivanic Acid Analogues. Part 11. Ozonolysis of α-Ethylideneazetidinones: Ozonide Fragmentation to α-Amino Acid-N-carboxyanhydrides

Bateson, John H.,Fell, Stephen C. M.,Kaura, Arun C.,Southgate, Robert

, p. 1577 - 1582 (2007/10/02)

Ozonolysis of (E)-7-ethylideneoctane-2-spirocyclohexan>-8-one failed to provide the α-oxoazetidinone 2, but afforded an α-amino acid-N-carboxyanhydride nonane-2-spirocyclohexane>-7,9-dione 5. octane-2-spirocyclohexane>-7,8-dione 2 was instead obtained from the trans-ketone 9 by a sequence involving Baeyer-Villiger oxidation of the azido ketone 10.
