Check Digit Verification of cas no

The CAS Registry Mumber 136964-82-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,9,6 and 4 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 136964-82:
(8*1)+(7*3)+(6*6)+(5*9)+(4*6)+(3*4)+(2*8)+(1*2)=164
164 % 10 = 4
So 136964-82-4 is a valid CAS Registry Number.
