Check Digit Verification of cas no

The CAS Registry Mumber 73813-72-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,8,1 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 73813-72:
(7*7)+(6*3)+(5*8)+(4*1)+(3*3)+(2*7)+(1*2)=136
136 % 10 = 6
So 73813-72-6 is a valid CAS Registry Number.
