Check Digit Verification of cas no

The CAS Registry Mumber 89231-91-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,2,3 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 89231-91:
(7*8)+(6*9)+(5*2)+(4*3)+(3*1)+(2*9)+(1*1)=154
154 % 10 = 4
So 89231-91-4 is a valid CAS Registry Number.
