Check Digit Verification of cas no

The CAS Registry Mumber 87957-21-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,9,5 and 7 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 87957-21:
(7*8)+(6*7)+(5*9)+(4*5)+(3*7)+(2*2)+(1*1)=189
189 % 10 = 9
So 87957-21-9 is a valid CAS Registry Number.
