Check Digit Verification of cas no

The CAS Registry Mumber 73673-38-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,6,7 and 3 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 73673-38:
(7*7)+(6*3)+(5*6)+(4*7)+(3*3)+(2*3)+(1*8)=148
148 % 10 = 8
So 73673-38-8 is a valid CAS Registry Number.
