Check Digit Verification of cas no

The CAS Registry Mumber 87953-51-3 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 3 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 87953-51:
(7*8)+(6*7)+(5*9)+(4*5)+(3*3)+(2*5)+(1*1)=183
183 % 10 = 3
So 87953-51-3 is a valid CAS Registry Number.
