Check Digit Verification of cas no

The CAS Registry Mumber 81808-30-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,8,0 and 8 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 81808-30:
(7*8)+(6*1)+(5*8)+(4*0)+(3*8)+(2*3)+(1*0)=132
132 % 10 = 2
So 81808-30-2 is a valid CAS Registry Number.
