Check Digit Verification of cas no

The CAS Registry Mumber 21231-98-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,3 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 21231-98:
(7*2)+(6*1)+(5*2)+(4*3)+(3*1)+(2*9)+(1*8)=71
71 % 10 = 1
So 21231-98-1 is a valid CAS Registry Number.
