Check Digit Verification of cas no

The CAS Registry Mumber 98269-63-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,2,6 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 98269-63:
(7*9)+(6*8)+(5*2)+(4*6)+(3*9)+(2*6)+(1*3)=187
187 % 10 = 7
So 98269-63-7 is a valid CAS Registry Number.
