Check Digit Verification of cas no

The CAS Registry Mumber 2609-99-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,0 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2609-99:
(6*2)+(5*6)+(4*0)+(3*9)+(2*9)+(1*9)=96
96 % 10 = 6
So 2609-99-6 is a valid CAS Registry Number.
