Check Digit Verification of cas no

The CAS Registry Mumber 6781-79-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,8 and 1 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6781-79:
(6*6)+(5*7)+(4*8)+(3*1)+(2*7)+(1*9)=129
129 % 10 = 9
So 6781-79-9 is a valid CAS Registry Number.
