Check Digit Verification of cas no

The CAS Registry Mumber 83089-74-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,0,8 and 9 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 83089-74:
(7*8)+(6*3)+(5*0)+(4*8)+(3*9)+(2*7)+(1*4)=151
151 % 10 = 1
So 83089-74-1 is a valid CAS Registry Number.

The Chemistry of 4-Mercaptoazetidin-2-ones. Part 3. Synthesis of 6-Phenoxyacetamido-2-alkylidenepenam-3-carboxylic Acids

Osborne, Neal F.

, p. 1429 - 1434 (2007/10/02)

A general method for the preparation of α-bromoallenic esters (2) involving the reaction of an acid chloride with a carboxybromomethylenetriphenylphosphorane has been developed.Reaction of these esters with the 4-mercaptoazetidin-2-one (1) gave rise to the 2-alkylidenepenam esters (3).The title compounds, obtained by hydrogenolysis of the corresponding benzyl esters, showed only moderate antibacterial properties.
