Check Digit Verification of cas no

The CAS Registry Mumber 98770-72-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,7,7 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 98770-72:
(7*9)+(6*8)+(5*7)+(4*7)+(3*0)+(2*7)+(1*2)=190
190 % 10 = 0
So 98770-72-0 is a valid CAS Registry Number.
