Check Digit Verification of cas no

The CAS Registry Mumber 77210-12-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,2,1 and 0 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 77210-12:
(7*7)+(6*7)+(5*2)+(4*1)+(3*0)+(2*1)+(1*2)=109
109 % 10 = 9
So 77210-12-9 is a valid CAS Registry Number.
