Check Digit Verification of cas no

The CAS Registry Mumber 21206-64-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,0 and 6 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 21206-64:
(7*2)+(6*1)+(5*2)+(4*0)+(3*6)+(2*6)+(1*4)=64
64 % 10 = 4
So 21206-64-4 is a valid CAS Registry Number.
