Check Digit Verification of cas no

The CAS Registry Mumber 76203-21-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,2,0 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 76203-21:
(7*7)+(6*6)+(5*2)+(4*0)+(3*3)+(2*2)+(1*1)=109
109 % 10 = 9
So 76203-21-9 is a valid CAS Registry Number.
