Check Digit Verification of cas no

The CAS Registry Mumber 21298-65-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,9 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 21298-65:
(7*2)+(6*1)+(5*2)+(4*9)+(3*8)+(2*6)+(1*5)=107
107 % 10 = 7
So 21298-65-7 is a valid CAS Registry Number.
