Check Digit Verification of cas no

The CAS Registry Mumber 98977-19-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,9,7 and 7 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 98977-19:
(7*9)+(6*8)+(5*9)+(4*7)+(3*7)+(2*1)+(1*9)=216
216 % 10 = 6
So 98977-19-6 is a valid CAS Registry Number.
