Check Digit Verification of cas no

The CAS Registry Mumber 22563-51-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,5,6 and 3 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 22563-51:
(7*2)+(6*2)+(5*5)+(4*6)+(3*3)+(2*5)+(1*1)=95
95 % 10 = 5
So 22563-51-5 is a valid CAS Registry Number.
