Check Digit Verification of cas no

The CAS Registry Mumber 20261-64-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,2,6 and 1 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 20261-64:
(7*2)+(6*0)+(5*2)+(4*6)+(3*1)+(2*6)+(1*4)=67
67 % 10 = 7
So 20261-64-7 is a valid CAS Registry Number.
