Check Digit Verification of cas no

The CAS Registry Mumber 118738-91-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,7,3 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 118738-91:
(8*1)+(7*1)+(6*8)+(5*7)+(4*3)+(3*8)+(2*9)+(1*1)=153
153 % 10 = 3
So 118738-91-3 is a valid CAS Registry Number.
