Check Digit Verification of cas no

The CAS Registry Mumber 54509-99-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,5,0 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 54509-99:
(7*5)+(6*4)+(5*5)+(4*0)+(3*9)+(2*9)+(1*9)=138
138 % 10 = 8
So 54509-99-8 is a valid CAS Registry Number.

Stereochemical Studies. VI. Stereoselective Synthesis of trans-Fused Octahydroindene-1-carboxylic Acids

Galteri, Mario,Lewis, Peter H.,Middleton, Sydney,Stock, Lionel E.

, p. 101 - 111 (2007/10/02)

The trans-fused octahydroindene-1-carboxylic acid (9) having a pseudo-axial carboxyl group is formed in good yield on oxidation of 2-acyl derivatives of trans-fused octahydronaphthalen-1(2H)-one.On epimerization it yields the pseudo-equatorial isomer (3)
