Check Digit Verification of cas no

The CAS Registry Mumber 98690-54-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,6,9 and 0 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 98690-54:
(7*9)+(6*8)+(5*6)+(4*9)+(3*0)+(2*5)+(1*4)=191
191 % 10 = 1
So 98690-54-1 is a valid CAS Registry Number.
