Check Digit Verification of cas no

The CAS Registry Mumber 40098-40-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,0,9 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 40098-40:
(7*4)+(6*0)+(5*0)+(4*9)+(3*8)+(2*4)+(1*0)=96
96 % 10 = 6
So 40098-40-6 is a valid CAS Registry Number.

3-(Optionally oxygenated)-5-oxocyclopent-1-enealkanoic acids and their alkyl esters are allowed to react with appropriate alkenyl copper, alkenyl boron, alkynyl boron, alkynyl gallium or alkynyl aluminum compounds to produce the corresponding 2-(3-hydroxy-3-optionally alkylated!-1-alkenyl)cyclopentanealkanoic acids, 2-(3-hydroxy-3-optionally alkylated!-1-alkynyl)cyclopentanealkanoic acids and their esters. The prostaglandin derivatives so produced are valuable and useful as pharmacological agents as is evidenced by their central nervous system-affective, anti-bacterial, anti-fungal and prostaglandin antagonist activity.
