Check Digit Verification of cas no

The CAS Registry Mumber 918140-64-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,8,1,4 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 918140-64:
(8*9)+(7*1)+(6*8)+(5*1)+(4*4)+(3*0)+(2*6)+(1*4)=164
164 % 10 = 4
So 918140-64-4 is a valid CAS Registry Number.
