Check Digit Verification of cas no

The CAS Registry Mumber 137959-30-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,9,5 and 9 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 137959-30:
(8*1)+(7*3)+(6*7)+(5*9)+(4*5)+(3*9)+(2*3)+(1*0)=169
169 % 10 = 9
So 137959-30-9 is a valid CAS Registry Number.
