Check Digit Verification of cas no

The CAS Registry Mumber 93680-50-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,6,8 and 0 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 93680-50:
(7*9)+(6*3)+(5*6)+(4*8)+(3*0)+(2*5)+(1*0)=153
153 % 10 = 3
So 93680-50-3 is a valid CAS Registry Number.
