Check Digit Verification of cas no

The CAS Registry Mumber 78464-38-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,4,6 and 4 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 78464-38:
(7*7)+(6*8)+(5*4)+(4*6)+(3*4)+(2*3)+(1*8)=167
167 % 10 = 7
So 78464-38-7 is a valid CAS Registry Number.
