Check Digit Verification of cas no

The CAS Registry Mumber 677020-92-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,7,0,2 and 0 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 677020-92:
(8*6)+(7*7)+(6*7)+(5*0)+(4*2)+(3*0)+(2*9)+(1*2)=167
167 % 10 = 7
So 677020-92-7 is a valid CAS Registry Number.
