Check Digit Verification of cas no

The CAS Registry Mumber 118708-50-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,7,0 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 118708-50:
(8*1)+(7*1)+(6*8)+(5*7)+(4*0)+(3*8)+(2*5)+(1*0)=132
132 % 10 = 2
So 118708-50-2 is a valid CAS Registry Number.
